Is 327 Total GPH good enough for 20 gallon?

[surjer]

I just want to make sure. I have an Aquaclear50 HOB Filter on one side of my tank and an AquaClear20 PH on the other side of the tank. Is this enough circulation for the whole thing?

According to specs it says. ...

Aquaclear50 FILTER = 200 GPH
AquaClear20 PH = 127 GPH

That sounds about right. I would aim the powerhead so that it ripples or breaks the surface of the water a little bit.

For my 20 gallon I have two aquaclear 20 powerheads, one on each side of the tank pointing towards the front of the glass. Then in between those in the middle of the tank I have an Emperor 280 filter and then I have a Rena XP1 cannister filter blowing around in the back of the tank behind the rocks. My corals love it and i dont have any dead spots.

I use to run an aquaclear50 and 1 maxijet 600 (i tried two but didnt like that much current in there). That setup seemed good to me.
