Return Pump

[bangbangkhan]

I am in process of building my 90g reef. I cant decide on the pumps....the return will be 3/4" Loc-Line return and the overflow kit will be a Herbie design with two 1.5" pipes.

The glass-holes qualifies it as a 1500 GPH and based on my research the return pump should be just under the overflow rating.

I read online that 1.5" pipe has a flow of almost 1350 GPH and that 3/4" would have a flow of 337.50.

So what kind of a pump would be best for the return?

Eheim Universal 1262 or Danner-Mag Drive 1200 Supreme?

Cheers

I have almost the same thing,
CPR CS102 overflow box, with 2 1" bulkhead drains, with 1" flexible tubing, then a mag 12 return pump with a 1" return

Box and pump are both rated for 1200 gph, and I put a ball valve on the return line to control how much water is pushed through, if I didn't it would be pushing everything in the tank in a tornado

will my 3/4" return be enough to push enough water so the sump doesn't flood?

yeah it should.

 

[bangbangkhan]

so which pump is better? eheim or mag?

I've never had any trouble with any mag pump I've owned. Never used a eheim.
Looks like you are putting together a good plan.

I heard they are very reliable but I also read online that eheim are quieter than a mag

 

[over my head]

you wont flood your sump if your pump only flows 100gph than your tank will only discharge 100gph both brands are good pumps i dont think you could go wrong with what ever you choose
