Need inputs on return needed

[gpenley]

I am getting a 135 gallon tank with refugium, sump, etc, will have lots of soft and hard coral, T-5s, and need a return pump. The tank has two corner returns. How big of a return pump do I need? 500 GPH? 750? 900? 1000 or more?

thanks,

Gpenley

On my 120 I'm running a mag 12 with a scwd that alternates the flow from side to side about every 10 seconds.

700 to 1200 gph , mag 9 or 12 would be good

I have a 120RR with a Mag 9.5. Works great

agreed w/ all of the above...ideally one looks for around 8-10 times the turn over from the return pump. however keep in mind that whatever the GPH rating is for the pump, that numberdrops slightly for every foot that it raises. As long as the pump does its job at the min is what is desired. The rest of thecurrent and turn over should come from powerheads in your display.
