return pump size

[tropills]

hey all, I need to know what return pump size I need for a dual megaflow AGA
tank, 125 gallon, I'm thinking a mag 12 ??? it will only be returning from under the tank (in stand) thru the returns in the tank 3/4". what do any of you use ?
kinda need to know soon so I can get a pump ordered up.
Thanks

Did you check out the head loss and overflow size calculators here at RC?

I think that should be fine or even a step lower... you may have to dial it back a bit if you want to quiet the overflows

It's actually going to be a African cichlid tank, I just wasn't sure which pump to use, I kinda figured the mag 12, dont need any thing over kill, It will have a sump with java moss in the fuge tho. (kinda like cheato in a salt tank)...
