Coralife Biocube Protein Skimmer

Skimmer is great and works well.

This has worked out great for my situation. I lost five aquariums in a house fire, so I am starting over slowly. I started a 29 gallon cycling (mid June 23), and most skimmers were way too big. I did not want to set up a sump (and/or have the tank drilled). Not now anyway... As others have said; yes, this skimmer puts out tons of microbubbles, but those will eventually settle down. You will also need to mess with it (a lot) in order to find the perfect water level and adjustment of air flow. Mine took a few weeks to start producing foam. The suction cups hold tight, so it is easy to remove the chamber for cleaning. The biggest pain was I had to cut a piece of glass out of the canopy top, to make the skimmer fit properly. Overall, for smaller aquariums this seems to be the best stand-alone (not a component of a HOB filter), AFFORDABLE, skimmer on the market.

The product us great and cheap!! It has been 1 week and it is getting lots if gunk and dirty water. I would defenetly recomend. The 2 reasons i give 4 stars and not 5 is because the box looked old and had holes in it, and it does make micro bubbles which is getting less and less with time. Also the skimmer chamber should be a bit bigger since the gunk acumulates fast (have to clean it about every 12 hours) and the lid comes loose so i put a rubber band around it and it does the trick.

The quality of the product and its functionality is top-notch for its price. It works as expected. It produces bubbles and pushes the toxic protein to the top and skims as one would think. Make sure your tank is tall enough because the pump will be underneath the skimmer. I added a little bit of tubing to remove the pump so I can place the skimmer lower, therefore the water level is up higher. This setup will for sure migrate to a bigger tank, but this has been a lot of fun for the kids.

Great little skimmer and is working fine. Only issue is there is a very small collection cup with no tube or outlet for collected detritus. I can only run it ‘dry’, not ‘wet’ as it accumulates and fills the cup. This causes the collection cup cap to lift and fall off. It is a nice, simple little skimmer. Easy to adjust the foam. Seems built well and I have had no issues with it in the two weeks I have had it running. I use it in a bait shrimp 120 QT (30 Gal) cooler. Since I regularly have 6+ dozen 3” – 5” shrimp in it at any given time, it has an extremely high organic load. This little skimmer does pull a ton of detritus out, but overfills the small collection cup every day. For a light load tank small tank it would be fine. Overall I would recommend to a friend with a light organic load application.
