!!!!!!help me with my sump design!!!!

so im ready to start the plumbing from my overflows to the sump.tank is a 125g with a 55g sump. sump is divided into three compartmnts- skimmer, return, and refugium. i have two drains and two returns. whats the best/safe routing method from my two drains to the sump. i see few people tee off the return to the refugium and have both drains go to skimmer section, while i see others sending one drain to skimmer section and other drain to refugium. if i send one drain to refugium, should i tee it off to skimmer section as well ?

ps: should i use flexible tubing as much as possible or stick with pvc ?
thanks in advance fellow mates !

 

I have one drain going to my skimmer and one drain tee'd going partial to refugium and partial to skimmer.

I used all PVC.

I would go for PVC except for the return pump. Use some flexible tubing connected to the return pump and then ball joint, finally plumb it back to the DT with PVC. This will alleviate a lot of vibration from plastic on plastic.

 

Sounds good.

Another concern-

when running the drains to my sump, should i have the drain under the water line or above the water line. Initially it sits right at the water line causing a loud gurgle/splash/ coming into the sump. Any cons in having the drain go underneath the water line?

 

Definitely under the water. I have my drains going into the skimmer area and i have a small maxijet in the same area with a hose going to my refugium.

 

nice idea, got pics of your plumbing
