What size pump to use?

[monza]

My tank is going to be a just a little bigger, I'm going to run a ...

WP-MT4300SEQ22XSX-SW
Sequence 1000 pump 1/6 HP, max flow 3200 gph at 8.5 ft. that will be on a closed loop and a 4 way. I have a pump from my sump as well, a Aqua Medic 6500. I have another closed from my chiller that is a Aqua Medic 3500.

I'm going to have lots of flow I think. IMO I would run your 4 way on a closed loop and a small pump thru the sump.
