from all the tiny little air bubbles floating around my tank. Where are all these bubbles coming from——surface agitation? I'm running a H.O.T. Magnum Pro and the bubbles look like it's coming mostly from the Bio-Wheel and maybe a little from the outflow diffuser. How can I get rid of the bubbles or at least make it so that not so many come out. For the most part, the rest of my tank is pretty clear. It's the bubbles that make it look like there is dirty particles floating around my tank.
