Coralife BioCube Protein Skimmer v2 for Tanks up to 32 Gallons


Item #: ES8604

Ships Free!

In Stock

The Coralife BioCube Protein Skimmer removes dissolved organics from saltwater aquariums before they can fully break down and become problematic. As the skimmer produces microbubbles, elements of fish waste, broken down food, dead organic material, toxins, etc. are attracted to these bubbles and stick to them as they rise up to the skimmer`s collection cup, out of the water circulating through your aquarium in the form of skimmate.

The BioCube Skimmer includes a hanging clip that will easily install into standard aquariums up to 32 gallons in volume, and is also designed to work with BioCube aquariums.

Installation is quick with its included pump, adjustable air intake valve, and easy to remove collection cup.


  • Slender design
  • Self-priming pump
  • Cone shaped inner chamber helps transition skimmate upward.


  • Dimensions: 5"L x 2.375"W x 11.25"H
  • For aquariums up to 32 gallons

Yes, I would recommend this.

So So Skimmer

Pros: Effective at collecting waste

Cons: A little louder than expected.

I have a biocube 32. This fits perfect in chamber 1 or 2 but it is pretty loud. Adds significant noise my setup. So much so that I am thinking about running it on a timer at night. I may be overly sensitive as my tank is in my living room and we're right next to it but prior to the skimmer we didn't notice the tank at all. However, it does in fact remove waste. Since I set it up - each morning I have a collection cup with brown waste collected. I just with it was quiter.
