ways to plumb a refugium

I bought a little sump for $25 and turned it into a refugium water enters on one side and over a baffle then exits by a bulkhead. I was thinking on using a tee fitting at the end of the overflow box so 50% goes to the sump and 50% goes to the refugium but theres a ball valve to control it. the refugium drains into the return chamber of the sump so it doesnt go through the skimmer.
does anyone get what Im saying?
Is this a good setup?
Is there a better one?

Thanks.

 

Sounds good, pretty much the same exact why I run mine. Should work fine for you.

 

same principle as mine but i only run about 30-40%thru my fuge.

 

I only run about 10 gph through my refug and it does great!
