Airation for a large tank
I have my 180 gallon running and the guy at the store told me not to use an air stone because the simple fact that the water that runs over the bioballs is all the aeration I would need. He went on to say that when using a sump filter system the water is more saturated than most tanks with a HOB and an air stone.
I love the tank but I already lost 2 small fish to the overflows overnight. found them in the sump this morning. they must have jumped over. I never even thought about this problem.
