I decided to use two sponge filters in my 46 gallon, but I'm not sure what air pump I should use. I've never used a sponge filter before. I had an old Elite 800 and I connected it to them both, but its not able to put enough air out. Since I have two sponge filters should I get an air pump rated for a larger tank or just an air pump rated for 50 gallons or so?
