Circulation Pumps

[RyanV]

It has been suggested that I up my circulation in my 20g/75l planted tank. Currently I have a hang on power filter rated for 200gph. I am wondering what circulation pump to get and how much gph I need. The Hydor Koralia Nano is either 240gph or 425, what do you recommend I get? Also should I consider the Aqueon or Hydor circulation pump?

Thanks

Mm... Dunno... You already have 10x. It depends a lot on what stocking you have.

A marine setup, for example, would need up to 30x, while my discus setup runs on 5x

I would go with one of the maxi-jet pros. Either the 400 or 600, used in either configuration. Here's a link with more info.
