I made a few sponge filters for my fry tanks, I'm ready to start cycling them but was wondering if you put the air stone all the way to the bottom below the holes and sponge or just above the sponge, and the drilled holes. I seen people do them both ways, but on most of the "premium" pre made ones they have the air line attached right above the sponge. What's your method and why?
