Well, I just think with the bio-balls that they broke up the bubbles into tiny pieces and not as many were actually getting diffused. But, I did try it with sponge and filter floss and no small bubbles! I had to silicon a leak though (just a minor drip every ten seconds), so it is getting set up tomorrow!
