I have a 60 gallon with Three, an Emp 400 , penguin 350 HOT plus a Aqua Top internal filter...IFP 30 (for a Pond) rated at 356 gph
which I doubt it pushs that but works well.
I think the AquaClear 70 would be good, I have that and a Penguin 350 on my 30 gallon. Works great and you can set the media as you like......
Or the internal Filter...I'm done with Marineland for a while they are great but huge...The nice thing about the internal it was 20 bucks on Amazon I was expecting a lot less and got pleasantly surprised.
