DIY overflow and refugium

[Tony Holliday]

I currently have a 29 gallon display tank with 2 clown fish, a yellow watchman goby, peppermint shrimp, cleaner shrimp, Bangai cardinal, snails, crabs, torch coral, zoas, candy cane, leptos, platygyra, hammer coral, Duncans, and pulsing xenia. Recently I wanted to get away from my HOB filter and go to a sump/refugium. I built my own over flow out of PVC pipe following the King of DIY YouTube tutorial. I put a 10 gallon tank under my cabinet with a MJ1200 return pump. The pump can not keep up with the overflow and creates a very loud waterfall sound. I ended up putting a ball valve on the overflow to limit GPU rate. Still having problems tuning it. Any tips would be helpful. Also post everyone's small dumps and DIY overflows.

A larger return pump may be necessary. The MJ1200 is only around 300gph. I would think with head pressure you’d need to be around at least 450. I may be wrong but just a thought.
