View Full Version : Return pumps..

06-12-2008, 08:06 AM
well as my build is finally going in the right direction, I will be looking at pumps in the next couple weeks..

The display is 75 and my sump is a 54 (I am thinking of dividing it equally into skimmer/return/fuge)... I will have 2 Koralia 3's in the display to help with flow.. they should pump about 1700GPH..

What size pumps should I be looking at?

What size of holes do have for your drain? Generally speaking the bulk head size will be 3/4" smaller than the diameter of the hole you have.This will be the limiting factor for how much water you need to return to the display. Reef central has a head loss calculator you can use to help you figure out what the flow will be with all your plumbing after you decide on a pump.

I don't have the tank at home yet, but if I relember correctly, the holes are 1.5" (maybe 2").. I should be picking it up tonight, and will know for sure. The included plumbing that comes with the tank definitely looks 2"..

Did you get my PM about my plumbing idea Doug?
