Hello all. I set my daughter up a 3 gallon fish tank in November. It is one of those cheapy Hawkeye 360 ones. Well the pump stopped working. So I went and bought her another one thinking that it was a 3 gallon air pump. I get it home and hook it up and was like wow, that's a lot of bubbles. Come to find out it is a 5-15 gallon air pump. Will it be okay to use or should I take it back and try to find a 3 gallon air pump. The fish are acting a little excited (like they don't know what to do with all the bubbles.) Any help would be greatly appreciated. I don't want anything to happen to her fish. They are two glow fish and a tetra by the way. I am clueless...please help!
