sump plumbing help please

[fireman23]

Ok i am going to put a different sump under my stand and need some plumbing info/help. I have a rr 110. My sump will be 3 chambers skimmer, return, refugium. My drain from overflow will be 1 1/4 . It will be teed off to supply skimmer and refugium with ball valve on refugium side. My pump is 700 + gph. Not sure of exact gph. My sump will be 20 gal. I have the durso drain. Will the 1 1/4 be big enough or should i go smaller? Also my return will be 3/4. Is that ok or woukd bigger be better?

yes. both return and drain are big enough. There's a calculator
Drain/Overflow Size

Correction.. Drain from overflow is 1 inch.

Yup should be big enough. Had a similar set up on a 90 gal.

Although how do you fit all that in a 20 gal.

Biggest concern will be water level incase of power failure in sump

 

[Coraloliseffect]

That is running water level high for fuge and foot print for fuge. and leaving capacity for water to drain. I assume will be sockless?

 

[fireman23]

The skimmer section is 8 3/4 long with 9 tall baffle the return is 11 long the fuge is 8.5 long and 10 tall with a bulkhead thst drains at 9 inches into return.

Will 1 inch be ok or should i increase drain and refugium plumbing to 1 1/4?
