[MrBanGa]

So I have a 70G tank 30x30. Right now I have a one power head it's aqueon 950 GPH . Is that two much flow or should I add another one ?

Depends on what you want to keep. You can probably add another one. Go for a controllable power head so you can adjust it to the tank inhabitants needs.
