Return Pumps

[Wolf DOT]

Hello,
I have a Deep Blue 120 gal RR with dual overflows. I believe the drains are 1-1/2" and the returns are 1". How do I know what size return pump will be sufficient?
i was thinking something along the lines of 1100 gph? just guessing

thank you for your assisstance.

I use the Marineland utility 5500 pump on my 120

I'd be shocked to find that you've got 1.5" & 1" overflow/return lines. The holes are probably that size, but that would accommodate a 1" overflow and a 3/4" return.

I agree with master swimmer. But you def have to find out what size drains you have. I believe a 1 inch can drain 600 gph. So dual 1 inch can drain 1200 gph max I'm almost sure. I think people usually shoot for 10 times turnover. Hope this helps

on my 120 i ran 2 genx pcx 30 without a problem.

On my 6' foot 120 fowlr I ran an Eheim 1262 dialed back, so you might be able to get away with the 1260. Nice quiet pump versatile in sump or out.

i have 120 and i run ehiem 1262 and its fine, i dont like a ton of flow threw sump anyway

If i'm not mistaking the bulkheads that come with that tank are 1", but then they have a barb fitting that is 3/4" inner diameter. I might be wrong, maybe Russ has one laying around to confirm.

yes (my mistake)that's it the the specs read 1" bulkhead fitting [slip/barb] and 3/4 bulkhead fitting [slip/barb] the hole dia is 1-1/2 and 1-3/4.
also I'm nervous about using the barb fitting and was thinking of changing to a threaded (wouldn't want a flood)

And also thank you every one for your input

I would change out those bulkheads, imo they are not good quality. I have help set up a few tanks, and if you over tighten them they strip easily.
A 1" bulkhead will drain 600 gph, without any restrictions, with personal experience I can tell you that 1200 gph is very loud. I would go with a pump rated for 3-5 times your dt.

+1 As always, sound advice.

Very Loud you say, any suggestions on how to deal with that? I saw this on reef central and was planning on using it.

What do you think? legitimate?

 

[rkaragozler]

It is a good product, but once again it all depends on how much water is going down the 1" opening of the bulkhead, the only way to be able to run say 1200 gph, and have it nearly quite is to go with a 2" bulkhead, now don't go crazy and try this , as that tank has a tempered bottom. the other option is to have an external over flow box with 2 1" drains, when you do this you actually have 4 1" drains handling 1200 gph, so in reality each one is draining 300 gph. that brings me back to 3-5x turnover for 2 1" drains, for a quite system. I don't think you bought a tank with internal over flows, and then to add external one.
