I'm putting together a new 20 gallon and have tentatively decided to do a trial run or a two or three jet UGJ system. I know it's a little small for one but I'm really just intrigued with the idea of it and want to try.

My question is how many GPH a powerhead should I get?

Thanks.

I am interested in replies on this as well. I started to do a UGJ system for my 20g long and when I was putting it in, it just seemed to take up so much space. Instead, for now, I have simply put in the power head to push water around. So far, so good, but we shall see.

I have an AC 30 in my 20long works well but is not as silent as I would have hoped. Very slight hum sound.
