Hello everyone, I have a question that maybe someone could answer. I recently purchased an Emperor 400 hob filter , to run as a secondary filter in my 90 gal tank . My main filter is a Filstar XP3. The Emperor has bio wheels and has been running since friday and I am getting many tiny micro bubbles in the tank. Could this be from the bio wheels breaking in? This is my first experience with biowheels. I tried adjusting flow rate and spraybar angle on biowheels and still get these tiny bubbles, hope they are not harmful to the fish. Does anyone have simular experience or suggestions of what i can do to correct this. Thanks in advance.
