Emperor 400, Penguin 350 or AC 110??

[Bderick67]

I want to add a hob for my 55 and 75. On the 75 I have a eheim 2026. On the 55 a wet/dry rated for a 75 gallon. Which ones should I get for my tanks?.......almost forgot right now in the 75 I have my 2 retics, arowana and 1 datnoid but they are going in a 220 as soon as im done cycling and in the 55 a green terror about 6-7 inches, he will go in the 75 soon.

Go with the AC110 they are better for mechanical filtration. With the wet/dry and the 2026 you already have great bio filtration so the Ac's would work nicely in your situation.
