how many gph for 2 1" overflows?

[b.crabby]

It's the other way around. How many gallons con 2 1" overflows handle. I have two in my ninty gal acrylic and i pump approx 1200 gal per hour and could probably pump more if my sump was directly under my tank or if i did'nt have ball valves on my overflow lines.

Thanks for the reply, i guess i looked into it too deep. Just like you said, i would like to pump enough to be able to handle their max draining ability.

How many galons per hour do i need to pump to keep up with 2 1" overflows?

Greg, the way over flows work is the water you pump into the tank, they will never drain faster than you pump. BTW, I think 1"=600GPH, if I am wrong I am sure someone will post the correct answer.
