i will be setting up a 55 gallon FOWLR tank was wondering what would best fit my tank. 2 750 gph power head/wavemakers or the 1 1600 twin wavemaker/powerhead pump. If I got the 2 I would place them on opposite corners facing each other but if I got the 1 I would place it in the back corner facing the front of the tank. Any suggestions would be great thanks.
