Pump for overflows ?????

[marinemarty]

Hi All, I am setting up a 125 gallon with twin overflows. Each overflow can handle 500 gallons/hour. What underwater pump would be enough for water movement back to the tank? The head on the pump would be 4 feet. Thank You
Martin

as Brommer stated, it's a little low rate for an over flow.
Where did you get that info?
How big is the tube/pipe?
If it fit 1" tube/pipe than it should be at 700 GPH. Twin tube should be a 1400 GPH.
LifeReef's twin tube(1" each) overflow rate at 1400 GPH.
CS102 over flow(2x1") rate at 1400 GPH.
And 125G with 1000 GPH overflow rate is a little low.

i got the following quote from AGA rep. "
Martin,
The corner overflows in the tank can handle 500 gallons per hour per overflow, the #29250 is just the accessories needed for plumbing the tank.
Your welcome,

that would turn my tank over 8 times per hour. is this not enough? cause it's already ordered, can i make up the difference in the sump/refug? thank you

More turn over per hour can be made up by the use of powerheads and such. don't sweat it. That will do fine. Just add a few powerheads, perhaps on a wave controller.($?)
