Whats the right filter for the tanks

[NJGourami]

I have two tanks and a selection of filters. a 75 african tank and a 55 flowerhorn tank. I have 2 xp2's an aquaclear 300, a penguin 350 and 200 and two 300 gph powerheads. Where would you guys put your stuff for optimal filtration on all tanks

I'd put one XP2 on each, then the AC300 on the 75 and one of the Penguins on the 55. Load up the upper media basket of the XP with bioballs or ceramic pieces for max biological filtration. I know you can put more bioballs in the AC, not sure about the penguins. As for the PHs, if you felt you needed one to stir up a dead corner you could do it, but I'm not sure they'd be necessary.
