Adding Another Filter? (AquaClear 20 or 30)

[RAWRRitsEDWINN]

Hi all. I want to add another filter to my 20 gallon tank, just for added filtration. I currently have a Marineland Penguin Biowheel 150 in there. I would like to add an AquaClear. I don't know which one to add though. Should I add the AC20 or AC30. One is for tanks 5g-20, while the other is for 10g-30g.

I'd go with the AC30.

I would go with the ac 30. Never know when you might want to go with a larger tank
