Fish Crazy
or
I saw this and had to ask this question. I'm using a "Penguin" 125 bio-wheel and have an air wand across the length of my 30 usg tank, creating a bubble wall . Looks pretty cool, but you're saying it's unnecessary? And should I consider removing it once I change over to a sand substrate? I am concerned it will stir up the sand.Bol said:airstones are never (except perhaps in the most extreme situations) necessary in a filtered tank.
