Just curious how many people use air pumps (just for bubbles) in their tank? I have a 44g and I like it better with the bubbles off, I think the fish do too...is it really necessary to have an air pump running? I have more than enough filtration through my filter...will that put enough oxygen in the tank? I've been reading that air pumps (on there own not hooked up to a filter) are not necessary and don't even put more oxygen into the water...anyways just curious AA to peoples thoughts on this
