Return pump advice

[angsess]

I am soon to be the proud owner of a fijicube 57 gallon ext. It is a dual return. It comes with the fiji-20 sump. The sump has one bulkhead into the return chamber. Should I be running 2 return pumps or one and splitting the output? If I need to run 2, how would it be plumbed? What pump or pumps should I be looking at?

One return pump is fine.
A Jebao MDP dc would be a good choice.

So plumb that to both return nozzles?

Congratulations on your new tank! We can't wait to see photos as you make a little progress.

think that bulkhead Ts off into the display yea? You only need to run 1 pump, It'll pump from sump up and T off into the two nozzles and into the display.

I run all jebao dcp pumps. No Wi-Fi or cool app they just work. They're quiet, reliable and cheap enough I buy two an have a back up. They have a manual controller for speed and it has a feed button which is all I need on a return pump.

I am excited. I have a 15 gallon cube that has been running almost 2 months now.

Is the 2400 enough at 660 gph or should I get the 3500?

Not sure about your tank. Usually if it's a system the manufacturer will have the max flow rating. I shoot for a little more than that since I can dial the pump down. I like more vs less as long as I can adjust it down like DC pump.

PS I ran a 3500 on my reefer 170 which was about 55g and I ran a 5000 on my reefer 300 which was about 80g

3500. Run it at half and go up or down from there.
I always try to aim for half capacity on any pump to push its longevity.

Nice! (Your Clown needs a Talbot as a buddy.)

You only need 2-3× tank volume, so say 200gph for your return.
Either will work.
