I need an air pump that will pump enough air for the following: 2 sponge filters 1 corner filter 2 large 2" air stones 1 small air stone My Fusion 400 will only operate 1 sponge filter which is pathetic or the 1 corner filter and small airstone. That's it. I need to find a new one ASAP as I have some ranchu babies coming my way tomorrow. I'd rather not have to go buy three small air pumps but I likely do need to buy them locally. But I'll take any advice you can give me. It will be located in my kitchen in an upper cabinet so it can't be too noisy.
