After looking through the options it looks as though the Eshopps Nano would be the only one to fit but would need to be located in the center pump chamber which could certainly cause some micro-bubbles.
I was looking at your videos of "Will it fit?" but couldn't find one for Innovative Marine Nuvo 16g my question which protein skimmer fit for this model? I don't think I want any of the Innovative Marine protein skimmers since they all have bad reputations and reviews. Also I dont want a HOB protein skimmer. Thank you!
