reliable return pump

[Aquattro]

I use a MAG 12 on my display and a Quiet One on my frag tank. Both close to same flow at 0' head, but the quiet one drops almost in half at 5', the MAG 12 stays at 1100gph at that height. Most internal pumps will be quiet, be sure to check the flow charts for the height you'll have to pump it to, generally 4 or 5 feet plus a bit for pipe friction.
