Innovative Marine BioSkim DC AIO Internal Nano Protein Skimmer - Universal

Very good

Great skimmer but this doesn’t last as much as 3 or more month. Mine just stopped working I tried to see if the motor is stuck or anything but still doesn’t work. Sadly, was a great product but doesn’t last as much :(. Also the cap does comes off when the skimmer comes half way on the chamber. But I put something heavy on top of the cap so it won’t spill the waste back into the aquarium.

Pro: great little skimmer when it worked. Small enough to fit in the second chamber of my JBJ 30. Con: pump died two after two weeks; skimmer no longer functions.

Further Edit 9/20 IM sent a replacement pump, which works fine right now. I am already preparing to send my business elsewhere in the future. There is no reason this pump should stop working after just months. Edit 8/29/20 AVOID this little skimmer. I loved this thing from the day I bought it. For once, I thought, a skimmer that actually does what its supposed to do, but I was horribly mistaken. The pump malfunctioned in just 6 months as is not repairable-at all. I should have listened to the other reviews that said this pump will malfunction and there are no words to explain the frustration. It is insane that they charge 45 dollars to replace this pump. It's almost like they know this is not a long term product. I have an email into them right now. If they make it right, as it is under warranty, I'll change it back to 5 stars I purchased this back in February as a replacement for the aquatic life nano skimmer, which was the worst purchase I have ever made. This skimmer has practically zero break in period. Within 2 days, the collection cup has already been collecting a fairly light skim. A week later and it's pulling out moderately darker, but still wet skim. This fits perfectly in the back chamber of my Cobalt CVUE 26. It's quite quiet and I have not experienced the micro-bubble problems that others have. This style of skimmer definitely works well for AIO tanks.

Wow, this is an amazing skimmer! It broke in and started doing its work within a couple of hours of having it running. Its effective and efficient for the compact size. Some extre notes about it. 1. You dont have to have the skimmer set at the specific water level said on the skimmer. I have mine sitting higher than what is recommended and it's still working amazingly. You just have to lower the collection cup to adjust accordingly. 2. The air hose assembly was interesting. Mine came with and extra air intake line, an elbow for the lines, and a silencer. Trying to figure out how it is ment to be put together will be interesting. Great pump overall, will be buying more for the rest of my fishtank builds.
