Good hang-on skimmers for the lower to mid-range budgets!
There are some decent low-to-mid priced protein skimmers, though each has its own little flaws and pluses. Yet there is an aquarist for each one. Some aquarists are simply more willing to mess around with their skimmers, so as Stuart Smalley would say, “and… that’s okay!”
Dating back to my newbie days in 2005 to the present, 2014, there are 3 skimmers that I have the most experience with. These skimmers I can say I have used for well over 6 months to 3 years, which is long enough, I feel, to justify reviewing them. Has it been almost 10 years? Wow, so much has changed in the saltwater world! Today there are amazing thermometers with a computer chip to monitor water temperature, turning it on or off for the exact temperature you want, and now we have LED lighting too. I have tried VHO, T5s, and Metal Halide; various substrates and tank sizes; and I have mixed various fish and seen interesting results.
I think we are all waiting for the “AquaScum 2003″ that dentist P. Sherman bought for his saltwater tank in “Finding Nemo”! Since I don’t like to speak on subjects I am not sure about, or a product I have not experienced, these 3 skimmers are the 3 hang-on or HOB (hang-on-the-back) I have had experience with.
I would put these three skimmers in the low-to-mid budget range and I can tell you that all three did their job. The lowest priced skimmer I used is now $80, it originally cost me $60 in 2005. The mid-range skimmer is about $180 today, and higher priced one runs about $260.
Red Sea Prizm Skimmer
I had a Prizm Skimmer for my first saltwater tank, which was a 55-gallon. Being new to the hobby I had spent quite a bit of money on so many things, including live rock. So of course I did what most newbies do, I bought a budget skimmer.
Mind you, I did do a lot of research on skimmers in the $50 to $100 range before I bought the Prizm Skimmer. I also read the “don’t skimp on the skimmer” suggestion along with countless other suggestions. So I went in knowing that someday I would have to upgrade. In my head, I had calculated that my 55-gallon tank, with 60+ pounds of live rock, would probably only hold about 40 gallons of water. So I decided this skimmer should do the job for now.
One thing I did right was to buy the cylinder shaped Pro Surface Skimmer Box along with the Prizm Pro. I will say, after about a month, the Prizm Pro did quite well for my needs. After weeks of tweaking and fiddling with it, I was able to have it product that dark nasty goo on a daily basis. Understandably, today most of us are very busy and don’t have time to “play” with our skimmers! A “plug and play skimmer,” the Prizm is not!
The surface skimmer box is what pulls in all the oils and goo from the water surface which saltwater fish and corals produce. The Prizm Pro Skimmer utilizes the adjustable height of the Skimmer box very well. Then an 18 blade turbo-Jet air injector sufficiently bubbles up the water to form skimmate for removal. Some nice touches with this skimmer are its slim, low profile and being available for about $100. That will include the surface skimmer box and a media chamber in which you can put carbon if desired.
Coralife Super Skimmer, Needle Wheel Protein Skimmer
By 2006 I was on to my 150-gallon reef tank. My UPS delivery guy kindly gave this huge tank to me. Yeah, that IS cool! He was delivering a package and saw my 55-gallon aquarium and asked if I would be interested in a 150-gallon tank. Of course I responded, “Why, YES I would, good sir!”
So my research for a new skimmer started up again. It needed to be another hang-on model because there were no drill holes in my new tank for a sump. Due to the location of the tank, size or bulk was not an issue. For inhabitants I had a Magnificent Anemone Heteractis Magnifica, which was about 5″ across when I bought it, and reaching 18″ across by the time it grew up. On top of that I had many other corals and lots of fish.
After a lot of research I settled on needle wheel technology, and purchased the Coralife Super Skimmer Needle Wheel 220, rated for 220 gallons. By now I had learned a few things about skimmers, so I knew that over sizing them slightly was not a bad idea. This skimmer pulled out some of the foulest smelling dark goo I had seen!
Yes, it works and it works well. On the downside, there was again, a lot of fiddling and tweaking. Inconveniently, you must turn the dial that is used for the bubble/skimming levels down all the way in order to clean the cup. This was a bit annoying, since it could take some time to find that exact “sweet spot” again for maximum goo removal! A simple fix that came to mind after the first few cleanings, was to mark the spot where the dial was set with a black magic marker, making it easy to find the original spot the red dial was set. The only time I had an issue with this skimmer was when I used products that caused mass skimmate production. And that is not the fault of the skimmer, but rather user error!
Even though the Coralife Needle Wheel Skimmer does not have a “surface” skimmer, it did quite well at producing that yuck we all want out of our tanks. By using the needle-wheel system with an aspirating Venturi, it caused tons of micro-bubbles and increased contact time, which is needed to be effective. Yes, initially there will be micro-bubbles in the tank, but don’t fret. Some adjustments, doing the hokey pokey, and making a few calls to Coralife will fix the problem. Their customer care is great.
Once you have it dialed in this is truly a great skimmer for the money. Currently the Coralife Needle Wheel Skimmer comes in a 65 gallon size for under $100, a 125 gallon size for about $150, and the 220 gallon size for about for $180.
AquaC Remora Protein Skimmer
Fast forwarding several years, I downsized my tank to a 60-gallon and again bought a Coralife. Due to limited space however, I needed to buy a new skimmer so the tank was not so far from the wall. This is when I bought the AquaC Remora Series Protein Skimmer. Currently, I have an AquaC Remora Pro Hang-On Skimmer rated for 50 to 120 gallons on my 75-gallon tank. I will say it gets out some nasty stuff, even with only 3 fish and 60 pounds of live rock!
What can I say… this is a great skimmer. This one IS “plug and play”, no muss no fuss! There is a break in period, as with all skimmers, but for the most part just adjust the collection cup for a darker or lighter skimmate (like you would the other two), and you’re done! The AquaC Remora uses a spray-injection. This is a powerful, high-pressure, air-induction spray that causes enormous amounts of goo removing bubbles.
I also purchased the skimmer box, which neatly hid the pump. This produced a lot of gooey icky skimmate and was easy to adjust by adding a thick round rubber band around the square cup. When it comes time to clean the skimmer cup you need to be careful not to move this band. However it isn’t a big deal if you do move it because the skimmer responds quickly to adjustments. The boxes are sized appropriately for the differently sized skimmers and pumps. You can also use the smaller pump and the smaller box with the larger skimmer, but that would just be silly. The square design does make it a little more challenging to clean, but hey, if that is the worst of it, I’ll take it. Plus this skimmer will not overflow!
The AquaC Remora Pro Hang-On also has a drain option for both sizes, which will drain into a 5-gallon container that is hidden under the tank. I recommend getting it, especially for those vacation days. But if you choose not to use the drain, you can just turn it upward and put a plug on it. The body of the skimmer has a special cut out area for the drain plug so this is not something you can do yourself.
I honestly struggled with my decision when it came to buying a skimmer for my present 75 gallon tank. Would I buy a Coralife or another AquaC Remora Pro Skimmer? Well, the flat, wide rectangular design of the AquaC won me over. After all, the tank is already intruding in a walkway of my house, and if I added the Coralife, I may have had to build a bridge over my tank! Okay, so it isn’t THAT bad! One thing I also like about the AquaC is there are just 2 small sections you have to cut out of that black strip in the back of your glass lid if you have a cover! I am planning to buy a Snake Eel, and I need a completely sealed top! Upon researching the AquaC Remora Pro Skimmer, I stumbled across an ad in my local Craigslist! I scored one that was only a few years old for LESS than 1/2 of the retail price!
Their customer service is second to none! The skimmer started to produce aa lot of excess, foamy skim production that was basically a clearish tan. Perplexed, I called their customer service number only to find out the culprit was a product called “Instant Ocean de-chlor” which is great, but has a “slime protection” for the fish. They said most skimmers over skim when this type of de-chlor is added, so avoid any that say “slime coat or slime protection.” Besides the fact, our saltwater fish don’t really need that like freshwater fish do! I had forgotten that little bit of information! You will typically speak to the inventor or one of his well-qualified employees! He was happy to help me, knowing full well I got this last AquaC on Craigslist! I told him that just to see what his reaction would be and he could care less where I got it, but just that I was happt with the product!
The AquaC Remora Hang-On for 20 to 75 gallons runs about $160 and the larger AquaC Remora Pro, for 50 to 120 gallons, runs about $250. An additional $10 buys the Pro Hang-On with the drain fitting. AquaC now has a “new and improved” Remora-S for 20 to 75 gallons. I have not used that one, so I cannot comment on it, but it is supposed to be even better.
Getting the best with your skimmer
Removing the goo from the aquarium is important. Yet too large of a skimmer on any tank can cause over skimming, which is not good for your tank. There are natural things found in the water that corals and other organisms need to thrive. Many suggest, especially in Europe, that you turn the skimmer off at night once the tank is well established. Some find their corals do better with this action. Yet if the skimmer is under powered, turning it off at night wouldn’t be necessary. So basically this suggestion needs to be tempered with the size of the skimmer, the contents or bioload of the aquarium, and the tank size.
Gladly, many companies are now stating the size of the skimmer based on the size of the tank and it’s bio-load, which is very responsible! This makes a skimmer purchase almost dummy proof, and that is great because no hobbyist wants to buy the wrong thing.
What are your protein skimmer experiences? We all should experiment to find a happy medium with skimming, and with discovery, share our new observations with others. This is how we all learn because no one knows everything! Happy skimming!

A beautiful bright red coral species, described as Psammogorgia hookeri, has been found in the Peruvian region of the Eastern Pacific!
It was the brilliant reddish color of this soft coral that first caught the attention of Yuri Hooker in 2002, and he collect the first specimens at that time. Hooker came across it again in 2008 while he was researching marine sponges, and at that time he was able to collect new specimens.
Dr Yuri Hooker is a biologist and naturalist at the Cayetano Heredia Peruvian University in Lima, Peru. In an article published by El Comercio, A new species of coral inhabiting the waters of Paracas, he says that with the 2008 specimens he began to “start the scientific process of identification and description”. It was then validated as a new soft coral species in 2014 by Odalisca Breedy, a research specialist in Octocoral Taxonomy at the University of Costa Rica (CIMAR), and her associate Hector M. Guzman, a marine biologist with the Smithsonian Tropical Research Institute (STRI).
This new coral species has been named Psammogorgia hookeri in honor of Dr Yuri Hooker. Breedy and Guzman describe this honor in their report, A new species of alcyonacean octocoral from the Peruvian zoogeographic region, published by Journal of the Marine Biological Association of the United Kingdom 2014, as bestowed “in recognition of his (Hooker) indefatigable and valuable contribution to the knowledge of the marine invertebrates and natural history of Peru.”
Breedy and Guzman, both experts in soft coral taxonomy and ecology, identified this new species based on colony characteristics and examinations using both light and scanning-electron microscopy. This species is described as a member of the Alcyonacea order of soft corals in the Holaxonia suborder of gorgonians. It belongs to the Plexauridae family, which are soft corals that form branching colonies and are often known as sea rods or sea fans. Within this family it is placed in the genus Psammogorgia, which now contains 14 described species, with Psammogorgia hookeri being the newest member.
The discovery of this new soft coral has created quite a stir. The rich coral red coloring makes it an undeniable beauty, but it seems to have a very limited occurrence. It has only been found from Isla San Gallan, in the Paracas National Reserve. This reserve is located in Ica, Peru and contains the Paracas Peninsula, coastal areas, and extends inland into the tropical desert areas.
This vibrant coral is thought to possibly be endemic to the Paracas National Reserve. During his research, Hooker says he has traveled almost all of the Peruvian coasts, from Tumbes to Tacna, but has only found these soft corals in the Paracas region.
The waters of this region are cool in contrast to the more congenial waters of other eastern Pacific tropical regions, where temperatures can exceed 82.4° F (28° C). Breedy and Guzman say, “the diversity of Peruvian shallowwater octocorals may be low, but species and ecosystems have adapted to dramatic coastal oceanographic changes.” They suggest that both “seasonal and inter-annual upwellings” and El Nino impact the region, changing the surface temperatures of the water. That in turn creates a “turbid green-to-brown ecosystem”, and thus effects the bio-productivity.
Description and habitat
Breedy and Guzman describe Psammogorgia hookeri colonies as small, bushy, and branching. They are about 3″(8 cm) wide with branches that reach about 7 3/4″ (12 cm) in length. They are a bright coral red color with translucent polyps.
The scientists described the coral’s colony habitation as clusters on rocky ledges and cliffs, and then spreading along the substrate. They say that areas they inhabit are generally “surrounded by other organisms such as sponges, worms, sea urchins and brachiopods among other sessile creatures.” However this coral is not a shallow water species. It has not been found at depths of less than 65′ (20 m).
Interestingly, this soft coral has been seen attached to mussel shells in local fish markets! However its availability for the reef aquarium is pretty slim right now, as finding Psammogorgia hookeri specimens in fish stores or online is difficult, if not impossible.

If you’ve ever had the opportunity to scuba dive, the area known as the “coral triangle” is a part of our world that offers a panorama of beauty to sate every artist’s palette.
Animal Planet, a unit of Discovery Communications, plans to share a bird’s eye view of the incredible life swirling beneath the waves of our vast oceans. “WILD DEEP” will be presented as a six-part televised documentary with the first episode featuring “The Coral Triangle” debuting on Tuesday, January 22, at 9:00pm ET/PT.
In the Animal Planet WILD DEEP press release they say the documentary will showcase “the amazing wonders and epic beauty that exist in Earth’s seas and oceans.” Their first episode will start “with a deep dive into the waters of the Coral Triangle near Asia.” Subsequent episodes will involve “series dives into the waters surrounding Africa, Europe, Oceania and the Americas to showcase the dramatic, complex universes beneath their waves.”
The Coral Triangle covers 5.7 million square kilometers in the Southwestern Pacific Ocean. It is a roughly shaped triangular region encompassing Indonesia, Malaysia, the Philippines, Papua New Guinea, Timor Leste and the Solomon Islands.
Each episode of the Animal Planet documentary should be a fascinating adventure, but the Coral Triangle region will definitely be a highlight.
The waters of this area are teeming with vast and extremely diverse life forms. Besides being known as the “coral triangle” it is also called the “Amazon of the seas”, reflecting the great Amazon Basin region which is re-known for the extraordinary beauty and diversity of its own inhabitants.
When we see ocean corals and fish above water, viewed in the full spectrum of light offered by aquariums, photos, or videos, we can see the incredible colors they possess.
Yet under water, the red spectrum of light becomes reduced the deeper you go, and the animals present a much more even palette. A soothing elegance of interconnected color is created beneath the waves. Though not necessarily flamboyant, this natural deep-water setting offers an awesome, yet curiously comforting scene.
The The Coral Triangle Center states that “a full 76 percent of known coral species are found here and 37 percent of reef fish species.” Now that’s a lot of critters! There are extensive mangrove forests in the region. Mangrove swamps grow along coastal regions and have massive root systems that are efficient at dissipating wave energy, so they protect the coastal areas from erosion, storm surges, and tsunamis. But they also provide valuable nursery areas for all sorts of aquatic animals.
The reef areas are also rich in life, with animals ranging from corals and fish to many types of invertebrates and algaes. They offer spawning and breeding grounds too, for whales and dolphins, sea turtles, and huge fisheries. According to the Coral Triangle Center, the life encountered in this region has “sustained sea faring island people for millennia.”
The Center says that today this incredible habitat “is recognized as the global centre of marine biodiversity and a global priority for conservation.” The diversity of these reef are the seeding stock for future coral reefs, and can help “ensure adaptation as our natural communities respond to climate change and other global trends.”
GMA News reports that the Coral Triangle region has been recognized “as an area of acute ecological importance and of great concern by many governments”. Countries including Indonesia, Malaysia, Timor Leste, Papua New Guinea, the Philippines and the Solomon Islands have come together to form ‘The Coral Triangle Initiative’. GMA reports that the Initiative’s purpose is to urgently spread “ideas about sustainable fishing practices” and to set up “marine reserves across the region to ensure pockets of this fragile ecosystem are protected and allowed to thrive.”
Animal-World provides pictures and information on a large selection of Coral Reef Animals and Saltwater fish, along with detailed information on the care necessary to keep them in a marine aquarium or reef tank.

The Octo Mom pales in comparison to the Florida Keys Coral Spawn
An event that happens just once a year yet results in hundreds of thousands of babies. Imagine have just one such happening to produce all the offspring you could ever want! That’s the annual spawning of Elkhorn, Staghorn and other corals off the Florida Keys.
For just a short period of time each year, by a phase of the moon, thirty thousand coral colonies or more are synced-up and driven to reproduce. This happens in August or September, usually just a few days after a full moon.
Now that type of baby making is enough to stir the envy of any mom, Octo or otherwise! Granted, there’s not the same type of physical interaction mammals have, making babies in the animal world. There’s no dating or marriage, nor ongoing obligations.
Coral parents never actually have sex, nor do the mothers (or fathers) then host and provide sustenance for the developing offspring. Rather corals are sessile invertebrates that spew their gametes (eggs and sperm) into the ocean’s water column in one mass spawning exchange.
Buoyant gamete bundles float about the water column until they meet up with gametes from neighboring colonies. Cross-fertilization, resulting is baby corals, is then a happen stance event.
Coral Spawning, Gamete Bundles
Hundreds of thousands of fertilized gametes quickly evolve into coral planula, which soon becomes free-swimming larvae. A few days later they will begin making their way down to the reef. They will seek a suitable area to on the reef area to settle, attach and form polyps.
These polyps grow into beautiful new coral colonies, expanding the reef.
Coral spawning is a curious event similar to being in an upside down snowstorm. Tons of tiny little flakes begin swirling about. But corals only spawn at night, so to watch this wondrous “dance of the gametes”, it helps to be a scuba diver. It also helps to be experienced in diving at night so that you don’t miss any of this exciting event. This years spawning lasted for 4 consecutive days.
Restoration of Corals in the Florida Keys
The Coral Restoration Foundation (CRF), based in the Florida Keys, has been working to restore various threatened coral species. I had an opportunity to see some of their cultured specimens of staghorn corals just a few weeks ago at the SuperZoo trade show. Ken Nedimyer, president of the foundation, was very excited about their ongoing efforts in creating offshore coral nurseries, as well as an onshore lab for studying reproduction.
For this years spawning event, CRF joined with 8 other organizations from across the country. Representatives from Akron Zoo, California Academy of Science, Florida Aquarium, Mystic Seaquarium, NOAA, Seaworld and Disney Worldwide Conservation Fund joined with CRF to provide help and support. 25 people in all worked to collect spawn from the open waters as well as from selected staghorn specimens spawning in their lab.
During a Coral Spawn
You and I, and everyone are invited to volunteer and participate in CRF dive programs to help plant specimens. Although the spawning season has passed until the fall of 2014, the restoration efforts are ongoing. The ultimate goal of CRF is to test the fertilization of selective gametes in an effort to propagate more resistant corals and help ensure their survival.

“I’m related to the beautiful Fire Coral, but without its fiercesome sting!”
The California Hydrocoral has many brilliant color variations, including a
The California Hydrocoral Stylaster californicus grows in many different formations. They can have tangled and dense networks of brittle branches or have pointed tip and delicate lace-like formations. They have a variety of colors from orange to purple and pinkish purple, and these are most attractive on a smooth surface.
These corals can be arborescent (tree-like) or encrusting on occasion, but generally are more delicately laced branches which grow on the same plane. Stylaster corals have smooth surfaces with thick tissue. Most of their common colors come in orane, white, yellow, purple, and pink with white margins. Their colors are known for being quite bright. Other names the California Hydrocoral goes by include just the Hydrocoral, the Fire Coral, the Lace Coral, and the Rose Lace Coral… Read More
Giant Sun Polyp
“I’m the largest button polyp out there, with a small bit of sunshine too!”
The Giant Sun Polyp is the biggest Zoanthid with its large oral disc!
The Giant Sun Polyp Protopalythoa grandis, is also called a Zoanthid. It is one of the very attractive button polyps. Their colors include white, green, and brown mottling. Iridescent coloring is also not uncommon, with occasional striations which look similar to wagon wheels. The Giant Sun Polyp is considered to be one of the largest Zoanthid species, just like most of the other Protopalythoa genus. Because this polyps oral disc can reach up to 2 inches (5 cm) in diameter, this polyp is actually thought to be the largest one of all.
In fact, it is not completely agreed upon as to whether the Giant Sun Polyp belongs to the Protopalythoa genus or the Palythoa genus. Originally they belonged to the Palythoa genus, but were later switched to the Protopalythoa genus because of their growth form. But now there are experts believing they should go back to the Palythoa genus and consider them to be. The scientific community has not yet settled completely on one or the other… Read More
“What’s the best way to have a blast?… Consider adding a Blasto Coral to your aquarium!”
The Blasto Coral is a unique coral and is popular among aquarists!
The Blasto Coral is one of the Blastomussa Corals and they have many color variations. The Blasto Coral Blastomussa wellsi is actually one of two Blastomussa corals that many people like. The other one is the Pineapple Coral Blastomussa merleti.
Most people actually prefer the The Blasto Coral B. wellsi over the B. merleti because it can be aquacultured into many colors – such as purple, green, pink, red, yellow and occasionally blue, as well as a many combinations of these colors. But it does have downfalls, such as being more difficult to care for and maintain. This coral also goes by the names Open Brain Coral, Swollen Brain Coral, Wellsi’s Brain Coral, Blastomussa Coral, Big Pipe Blastomussa, Pineapple Coral, and Blastomussa Wellsi… Read More
“This is a sea mat type of button coral! They form clusters of polyps on “mats” of sand!”
Moon Polyps received their name from the way their clusters of polyps appear –
in the shape of half moons!
The Moon Polyps Palythoa sp., are called by other names as well, including Encrusting Anemones, Sea Mats, and Zoanthid Button Polyps. They are actually colonial anemones and are fairly common in home reef aquariums. This genus alone, however, has lots of variety. They have polyps which are partially embedded in a mat and are quite short. Every polyp has flat discs that are covered with tentacles on their rims. Some species have tentacles which are very long and thin while others are knobby and short. Colors range from white, yellow, brown, cream, coffee, or yellow!
Palythoa sp. have a “mat” called the coenenchyma which connects the polyps. These polyps have little parts of sand and/or sediment that they use in the mat to make it more stiff and easier to support a colony. These extra bits of sand and sediment which make up the debris account for about 45% of the weight. The colonies grow in half-moon shapes (convex) and grow anywhere from 4″ to 12″ (10 – 30 cm) in diameter… Read More
Corky Sea Finger
“This coral actually gets its shape by growing on and over other Gorgoninas – which makes him more “quirky” than corky!”
The Corky Sea Finger reproduces easily and is quite easy to care for – making it a great
The Corky Sea Finger Briareum asbestinum, also goes by the name of the Purple Corky Finger. It is quite beautiful and has a finger shape, which is helped formed because it actually grows over and on other gorgonian species. These Gorgonians thrive in many conditions and are native to areas all over the Western Atlantic Ocean, including pristine and clean waters as well as more nutrient rich areas of water. They most often inhabit knee deep shallow waters. These corals are extremely popular and are collected more often than any other species. Other names this species goes by include the Purple Corky Finger, the Caribbean Corky Finger, the Moss Coral, the Deadman’s Finger, and the Sea Stalk Briareum.
These Gorgonians have another neat quality – if they have green tentacles with a purple base, then they have a fantastic glow when kept unter actinic lighting! The mat of the Corky Sea Finger is usually tan or purplish and gray with calyces that are basically just nubs and which are slightly raised… Read More
“What looks like a head of Romaine lettuce, but feels like a rock? You got it…me!”
The Leaf Coral is another coral which makes a great beginner coral!
The Leaf Coral Pavona decussata is attractive and has a frilled appearance. Quite like the Cactus Coral P. cactus, it has upright and flat fronds but they are thicker and not quite as twisted looking. Horizontal plates can also be formed. It has a surface that looks spiked due to tentacles that are spindly and pointed. Colors come in anything from brown, to green, to yellow cream. Other names for the Leaf Coral are the Frilly Coral, the Lettuce Coral, and the Cactus Coral. Other specimens of the Leaf Coral that have been aquacultured have names such as Green Pavona Decussata, Green Decussata, or Pavona Sp.
The genus which this Leaf Coral belongs to, the Pavona genus, typically has corals with small polyps stony (SPS) and are best for starting aquariums with. They do best with strong currents and high lighting but can also thrive in more moderate conditions… Read More
