Looking to buy power heads what brands are best for a 20 gallon tank and looking for ones that wont be to big and that wont take away from the overall tank?
I like hagen aquaclear, I have some very old ones. I will go down on record as saying the azoo powersweep, does not work in a reef tank. They may or may not be wonderful in freshwater, but they just do not last in a reef. Like 6 months to 9 months at most. I hear Maxis are wonderful as well I just have never bought them so I dont know personally.
I like maxi-jets too... if you ever want to use a wavemaker, the maxi-jets are hands down the best choice for they can withstand the constant turning on/shutting off.
