I'm running a CSL T3 (~700GPH after it T's off and comes back into the tank) on my 37G cube as the return.

OK got to add an additional comment here. don't worry so much about your return pump. to size it you want to get over 5X / hour turnover in the tank (closer to 10x is better) anymore than that and you have to do some pretty fancy plumbing to keep it from acting like a pressure washer.
my suggestion would be to set up an approx return rate of 10X then use some of the new power heads available like the tunze and the new Rio seio to give your tank current. I have an approximate current flow rate in my 94 gal of over 52X per hour and when I install the two new Rio sieo's in the tank it will increase my flow rate to 72X (6480 gal/hour) I'm hoping that will peal the mushrooms and button polyps off the rock  this doesn't include the mag 12 driving my chiller/UV or the mag 12 driving my other tank from the common sump, or the MAK4 driving my skimmer, this is just main tank current.

It is sort of relevant what your tank size is and your pump but more important is how much head loss you have for that pump with "your" tank.
http://reefs.org/pumps/ -a really good head loss calculator. (head loss is the over all flow loss from height and other plumping) The flow depends on what you want to keep. For SPS the min. suggested is 10X your tank volume. Some peple run way higher then that. My tank I'm planning now 250g, I'm trying to get at least 3000 gph of flow. Two pumps from the sump, two closed loops. Hope that helps. I've been reading way to much regarding pumps lately trying to decide which ones. It's the only decsion left and item to order for my tank.
