Sup guys and gals. I have a 55 long that is pretty well stocked. 6 dats, 1 silver arrow, 4 clown loaches, 2 archers, and 2 plecos. I will be upgrading to a bigger tank as soon as space permits. I am currently running an AC 110 and a marineland powerhead 300gph. My question is, should I get another power filter to complement my ac110, or should I get a powerhead with a quick filter attachment rated at 550 gph? I am leaning toward another aquaclear filter, maybe a ac50 or ac70. Thanks in advance. Any input is greatly appreciated.
