The Prizm Protein Skimmer made by Red Sea is a competitively priced skimmer that is designed to hang on the back of the tank. There are a few different models of the Prizm Skimmer available:

Prizm Protein Skimmer

Prizm - for up to 400 liter/100 gal tanks, hang on tank
Prizm Pro Deluxe - for up to 1200 liter/300 gal tanks, hang on tank or in sump use, also includes a surface skimmer and refillable media basket for biological and chemical media

The Prizm Protein Skimmer comes with an external water pump that attaches to the bottom of the unit. The neat part about this skimmer is the two stage reaction compartments where the water is first forced upward through the first compartment and then downward in the second compartment. This cross current allows the tiny air bubbles to have longer contact time and therefore more protein rich foam when it arrives at the top of the skimmer collection basket. Check out the animation on the Red Sea website for more information on how this skimmer operates.

Setting up the Prizm Protein Skimmer was rather easy and it took about 15 minutes to have it fully operational (it helps to read the directions first). The only thing you need to regulate or adjust with this skimmer is the water flow. This is done by turning a valve located on the top of the skimmer's water intake pipe. The more you open up this valve the faster the water will flow through the skimmer. With the increased water flow will come an increase in the noise level put out by this unit. The amount of noise produced by this skimmer could be compared to the amount of noise produced by an aquarium air pump. It wasn't too noisy, but you could definitely hear it running.

After running the Prizm Protein Skimmer for 10-12 hours we noticed a nice amount of dark brown skimmate in the collection chamber located at the top of the unit. Removing this chamber for cleaning is very easy to do. You simply have to twist it off, rinse out the collection chamber and twist or push it back on.

The Prizm Pro model comes with a surface skimmer which should provide even better skimming results than the regular model.

Protein Skimmer Comments

From: Dave D.
The Prizm model is a decent skimmer for the price. It worked well while I used it on my 55 gallon, but I've since upgraded to the Aquac Remora taking the advice of friends in the hobby. I would recommend spending the 50 - 60 percent more if you can and getting the Aquac. The amount of gunk in the collection cup in the remora model is way more and I have to clean the cup more often but it gives me peace of mind knowing that it's removing the amount of stuff that it does.

I tried this skimmer first and I felt that it was a hassle to have to continually mess with the valve. I took it back and tried the aquac remora and it was well worth the extra money.

I bought the $100 model, the regular size Prizm Skimmer, and it worked ok for a couple of months but then started to leak. I tried for several hours to isolate the leak but could never pin point the exact location. I think it was leaking towards the top right on the front of the skimmer where the plastic is fused together. To replace this skimmer, I got the aquac remora after reading the reviews on it and WOW! It cost me $150 plus shipping but it has pulled out a lot of brown stuff in the month I've been using it. I'm having to clean the collection cup about every 4 days. The only drawback to the aquac is that I'm still getting micro bubbles in the tank. The aquac pre-skimmer is supposed to alleviate that problem and I'm considering getting it.

These are really weakly made. I cracked the body of the skimmer while washing it. It got very loud and was a pain to set correctly. I would spend more money and get a euro reef or an asm instead of buying this one and having to replace it 6 months later like I did.

Do not waste your money on this skimmer! You're going to adjust the water flow every 2 hours. Either there's too much water flow or there won't be enough. I've never had it where it's skimming for a consistant amount of time. Also, this skimmer is loud as heck. Do youself a favor by buying a AquaC Remora. Iit is worth the extra $50.

1. The skimmer works well if you put a valve on the end of the intake air tube and throttle down the intake a bit.
2. Clean the reaction chamber and intake assembly every 3-5 days.
3. Do not put it on anything larger then a 40 gallon tank.

I have 2 of these hanging on the back of a 55 for over a year with no problems. The trick is learning to set the valve and then rechecking the setting like 10 minutes after. For those on a really tight budget they are OK but the aqua c remora (linked below) is a much better choice
