    ok I am planing on setting up a 125 with duel over flows.
    under it I want to put a 75 refugium (I am think sand live rock and chetto) with 1 over flow dumping into a filter sock in the 75 and a drain at the opposite end. That drain will dump into the sump, a 40 by the return pump.
    I will also have the other over flow being dumped into the 40 with a skimmer in the middle and a return pump at the end.
    Questions
    would that be to much water flow through the refugium area? how much flow rate would be best?
    would that be to much water flow through the skimmer area? how much flow rate would be best?
    in the refugium is using sand, live rock, and chetto good or do I not want to use all of those things?
    are Tunze Silence return pumps a good one. or what do others suggest
    when a tank has 2 over flows do i need 2 return pumps or will 1 work with a T?
    Thanks for your Ideas.

    i am going to use 1 pump with a T and it will have about 4x the turnover rate of the tank after the headloss...i'll be using a 900gph eheim pump. Joe from AE said this would work well and i trust his opinion.

    This is what I plan on doing since I have a similar tank design. I plan on having the 2 overflows connect and they will drain straight into my sump, from there the flow to my refugium will be coming from the the return pump with a "T" and a valve to reduce the flow going in, kind of like this set up

    Nope, 1 pump works, as far as a "T" might have to for returns, I try to stay away from tee's and 90's, This build I plan on using sweeping 90's, true Y fittings, and 45's.

    This is the setup I currently use and personally, I would not go this route again.   I think the T results in a lot of pressure loss.
    I plan to re-do my setup using 2 smaller pumps and as few bends/turns as possible.

    The T does result in a lot of pressure loss, but if it's throttled back properly, it can still work. It does take some tuning for sure. I had my carbon and GFO reactors running off of my return pump and when I added my frag tank, it cut flow to the display too much. I ended up adding a separate pump for that and when I reconfigure things this coming weekend, I'm going to use a bigger pump to put everything on the same return line again. There's a million different ways that you can set things up successfully and there's pros and cons on both sides.
