This item has been discontinued.


Protein skimmers have become a standard component in saltwater and reef aquarium filtration systems as they are very effective at removing dissolved organic compounds from aquarium water.

The Coralife Super Skimmer is a high-performance foam fractionator designed with a patented needle-wheel impeller and aspirating venturi. An improved energy saving pump increases the performance of the skimmer without increasing power demand.

The needle-wheel system creates a spiraling vortex of water and micro bubbles inside the reaction chamber where the bubbles attract fine proteins and organic compounds and deposit them in the collection cup. Advanced cone-shape design allows for unrestricted foam flow towards collection cup. This flow pattern naturally reduces the amount of water between air bubbles as the foam rises to efficiently produce a drier more productive skimmate in the collection cup. The result is a clean and healthy aquarium environment.

  • Patented needle wheel aspiration system using Posi-Flow pump
  • Powerful, yet quiet internal pump reduces footprint
  • Wide Neck Collection Cup with easy twist feature for effortless cleaning
  • Dual Injection Inlets increase bubble / water contact time
  • Wide Bubble Diffusion Plate uniformly disperses bubbles on bottom of reaction chamber
  • Oversized Air Inlet Tube reduces clogging and deposit build-up
  • Water Level Adjustment Dial for precision bubble production and water level control
  • Bubble Production Diffuser to prevent the flow of micro-bubbles into main aquarium
  • Dimensions: L12.25 x W8 x H22.5
  • For saltwater aquariums up to 150 gallons

design problems

I purchased the 300g skimmer as an upgrade for my 150g cold water tank. The cone attaches to a bottom flat plate with 4 thumb screws. When initially installed, the flat plate was warped and all the outflow from the pump leaked out between the plate and the cone. Sealed that with silicone adhesive and it works now. However the pump is noisy. Worse yet, the nut that attaches the collection cup to the cone has tiny threads and is almost impossible to align with the threads on the cone.... sometimes I give up and run the skimmer without being able to attach the cup to the cone and just let the cup set on top of the cone. Definitely do not recommend this skimmer and regret not returning it.

Coralife Cone Protein Skimmer

Delivered in good condition and assembly took less than 15 minutes. When I first plugged it in I had to check to ensure it was running as it runs very smooth and quiet. My previous skimmer had been down for over a month so there is no doubt some work to be done in my 150 gallon tank, after the break-in period I did some final adjustments and the cup has steadily filled since. Would recommend this product

High quality / mid-price

I am very pleased to report that I have had this skimmer on my 120 reef tank for 6 months. Initial setup was typical, however after the break in period I am verry happy with the level of skimmate this is providing me with. It is in a 120 mixed reef and continues to function flawlessly. 3/4 of a cup of thick dark skimmate is produced every 3 days. My water quality has never been better and my reef happier. 5 stars Corallife for a quality constructed product that out performs higher priced models with a much larger footprint.

coralife cone skimmer

I purchased this skimmer after the one I used for for 8 years stopped working which was not a coralife, this skimmer is much quieter than the last in fact I hear very little noise unlike the one I replaced once I get it adjusted properly I feel it will do a great job cleaning my 150 gallon tank

Great bang for buck

I was worried at first because I couldn't get the micro-bubbles to go below the collection cup like the instructions direct. I have it in 8.5" of water. After the break in period I no longer have level issues. The skim is now nice and dry. Once the tank is fully stocked I expect great performance! I did an extensive search for a skimmer over the last 12+ months. I wasn't in any hurry, but I needed something for my new 120gal tank I’ve been building. I learned that a cone skimmer has less back pressure on the pump for better skimming. I needed a skimmer that was under $300 able to handle a tank my size and shorter than 23”. This one fit the bill. I found two skimmers that could work, but decided that this skimmer was the best option after looking at all the skimmers on the market right now. I’m glad I chose this skimmer and at this point would buy again.
