Aeration in an Aquarium

[enzof9]

Hi, I was looking at my aquarium and thought it would look a lot better without two air pumps. My filter has a spray bar on it that agitates the water's surface pretty well, along with two air stones. My question is: do I need to have the two air stones in there, when my filter makes half-.3 cm (apx. of course :)) waves at the surface? Thanks

BTW: It's a 4ft tank

Well, if the spray bar is well above the water level and breaking the surface, the tank isn't nearly fully stocked, why not eliminate the air stones. If it turns out they need it, you will see the next day the fish gasping near the surface.

From what you said, you don't need the airstones. I do use them as I love to see a torent of bubbles in the corner of my larger tank...

If you have plants in the tank, then I would recommend just turning on the air pump (for the airstones) at night instead. If you don't have plants, then i don't think you need the pump.
