I have already said that it is a small protein skimmer that only works great for 16 gallons to 32 gallons aquarium. This skimmer’s built-in-filtration system can remove organic waste efficiently coming from fish, invertebrates, algae, and other biological processes. This skimmer is super effective on the biocube aquarium tank. Because it is made specifically for biocube aquariums. However, I have seen that it works fine on a similar tank that ranges from 15 to 32 gallons. The hanging clips and suction cups allow the skimmer to stay in the right position on the standard aquarium tank.

The included self-priming pump and cone-shaped inner chamber of this compact skimmer significantly enhance the overall filtration system’s productivity and skimming process. This effective surface skimmer ensures you making the tank water clean and healthy as much as possible.

There are many negative reviews out there, but in our close look and after a perfect set up we found it worked excellently on a biocube aquarium and a reef tank. After a new installation, it may take a few days to works perfectly and pull out the skim. 


This second innovation of the coralife protein skimmer is designed kept in the first chamber in the aquarium. Its sleek and slender design helps create adequate microbubbles, efficient skimming, reduces phosphate levels, removes harmful organics, and controls excessive algae growth through its quiet operation. Compared to its previous version, the coralife protein skimmer v2 comes with an upgraded airstone, heavy-duty air pump, and needle wheel impeller, which is more powerful and energy-efficient.
