I just got a HOG.5 for my nano cube 28 with two oc. clowns, 1 firefish, 1 cleaner shrimp, 2 RBTA, softies, LPS (candy cane and frogspawn) and one SPS (pink birdsnest).

I've read that bubbles in the main can be a problem for some creatures in a tank. If you put a UAS (HOG.5) in the display, how many bubbles are too many?? Which fish, inverts, corals, etc. respond negatively to bubbles??
