Return Pump How to Choose

[mnm1953]

Setting up a 90 gal with sump/refuge. Looking to use the CPR CS102 overflow box. It rated at 1200 gph. What do I need to be looking at for a return pump.

Thanks You People here Are great.

3-5 x the display. in your case 3-5 x 90 = gph. i would say an ocean runner 2500 good for 650 gph.

it is for the 90? why does it say 90 fresh?

[mnm1953]

I am converting to salt. I will be changing that now

Check the head loss calculator on the home page, bottom left. What type of pump are you thinking external or internal?

[mnm1953]

External Thanks for the head loss calculator

[brians4671]

my suggestion was an internal pump mnm...

[mnm1953]

From another site it was suggested the Eheim 1262 which is 900gph would this be to much. Could I use a ball valve to control the return flow. Anyone using this pump.

I think you would be fine with that pump, Ehiem are pretty hard to beat Internal or External.

I'm using the 1262 on my 180g. I guess you can use this pump if you'd like. the turnover is a little bit much for a 90g imo. but you can always T it and use it towards other things such as reactors etc... I think that if you want external, I"d go with something else rather than an eheim, just my preference. I like the eheim to be internal. small external pump, I'd go with iwaki. if you want bigger external pumps, I'd go with reeflo sequence.
