cheers, Charlie

indeed... you do not need a bigger pump to run the sump loop. Leave your CL pump to do the heavy duty while keeping your sump quiet and smooth running

But please do not tee the overflow drain. Ever. Never! A simply dreadful notion for many reasons re: complicated plumbing, handicapping the downstream skimmer, etc.

As for the overflow drains... you may want/need to keep these too. While you do not need a large sump pump, you do want large/quiet overflow drains. Displays are too commonly underdrilled. One 1.5" drains may handle the mag 9.5 at the head you likely have on it... but it will be operating on the high end of the range. Too risky for me. Drill a 2" hole or stick with your original plan for two 1.5" holes.

FWIW... I never liked refugia integrated into sumps. Too cramped, limited production from such small refugia... and unduly restricts sump proper volume/buffer.
