Pump Me Up!

[Mikey B]

Hi folks. New Guy here again with another question for my Calgary friends.
((Thanks for the great responses on my other questions.))

My tank is ready Friday and my stand is being delivered Saturday....among the million things I still need, I really need a pump.

Tank is a 120G with an overflow at one end that has one 3 inch hole for outflow and two 1.5 inch holes for inflows. A 50G sump/trickle filter will go in the stand.

The plan is to slowly build this baby into a nice little reef tank with a few fish. From what you guys have taught me so far, I know lots of flow is required.

A skimmer will probably be added later (separate pump).
I will be using some powerheads for more flow once landscaping is done.

How many GPH should I look for and what pump would you recommend to handle the flow back to the tank thru the two lines? The tank will be in the living room and the quieter the better.

Thank you again!

Mike
