Hey guys could I get some help reviewing my sump, refugium design here? Please see attached file.
It seems i have a few options.
1- tee of main return to send controlled flow to refugium which would be elevated and gravity fed to sump- skimmer- return. I would still have an emergency drain.
2- tee off return to feed the separate refugium, let it gravity feed to main sump
3 - run both drains and one feeding the refugium would have a valve to control flow.
I have retained and painted inside out of my stand so far, painted the back of the tank, ordered all my lights. Just need to finalize the sump design.
