Return pump

[Mandee]

Hi guys I have a 220 gallon tank that I'm starting. I have dual overflows. The return pumps that the tank came with are RIO TA3148 (2)
Which are rate 642 GPH is this enough flow or pressure going back into the tank?
Thank you

You are gonna want bigger like around 1200-1500 gph for your 220
