Powerhead For A 20 Gallon Help
hey guys, i have a 20 gallon tank and need some flow in it. i have an aquaclear 50 on it right now but its not very powerful. i was thinking of a koralia 2 but it seems way to big for my tank, it will be an eye soar. is there any others that you guys would recommend? i don't really plan on keeping acros, just montis.
