I have started this week to cycle a 60g FOWLR tank. I have a Mangniflow 360, 40 lbs Caribsea sand, 60 lbs of Caribsea life rock. My question is flow. I have two Fluval CP 4 on order. Each head is 1375GPH. Is that enough flow? or is it too much. Until the heads arrive. I have one Marineland maxi jet 1200 (1300GPH) running.
