What size pump to use?
 

I.m not sure what size pump i should use for my oceansmotions 4-way unit
my tank is 66x24x30. Its going to be mostly SPS.

Is this going to be a return pump or a closed loop pump?

Its goin to be used as both, It will return the water through a 4-way unit.

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.

I'll be running a Dart on my 24x24x24 cube through my 4 way as a closed loop.

You might not want that much flow running through your sump or it may sound like the Mississippi.

Its going to be an in wall tank so noise is not an issue. And I dont have enough money to buy two pumps. so an ampmaster 3000 or whatever its called would be good?

3000GPH? Either the Dolphin Ampmaster pumps or Sequence pumps would be the most energy efficient and push out that amount of water. Just make sure it doesn't have to pump very high as they are flow pumps rather than pressure pumps.

I did a 'ton' of research regarding the Sequence and the Amp master they are both very good. I choice the Sequence for one reason seemed to be less complaints, mostly leaking seals.

Did you already buy your ocean motions? I have been reading a bunch of reviews about them lately, they seam pretty good but one complaint keeps coming up in that they switch to fast and people wish it could be slowed down.

Havent purchesed my 4-way yet, but as far as i know it will do one full rotaion in 1min. Actully ive heard people say they wish it would move faster. But im ok with the timing as it is. You think 3000gph is enough or tomuch. Also it only has to go up about 4 or 5 feet.
