Which powerhead (or heads) for 10g
I've got my 10g cycling right now, and I'm using an older Hagen AC 20 I believe (a little over 100 gph). I realize this is too low for my tank, what do you guys recommend I add or replace this with?
I was considering a Koralia Nano but it almost seems too much for a single powerhead on a 10g.
Thanks.
