Got a question regarding the drain holes in the overflow.
The overflow has Two 1.875" holes for 1" return pipes, one 2.625" for return on a 1.5" closed loop return (which Im not going to use) and one 3.25" hole for a 2" drain to sump...
Now my question, the 3.25" hole for the 2" drain pipe was designed to be used with a Reeflo Barracuda for return pump which Im not going to use, I want a smaller less energy consuming pump with a lot less flow.
Now should I cap/seal the 2.625" hole or the 3.25" hole, I got the bulkheads for both and just afraid that If I use a small pump with a large drain pipe it will make gurgling noises...
I would use the largest one. The noisiest drains I have had where small ones that I had at their capacity. I am using two 1.5" drains into a 3" drain pipe. The noise from my skimmer and return pump are louder.
I would keep those Reeflo pumps they are great pumps and work very well in a closed loop system and can be throttled back also.
Great start.. Looking forward to see the rest and all the best with your lovely build.
If you weld disks to the bottom of the tank no future user/owner of the tank will be able to let it sit on a flat surface. I would think that cutting disks to fit inside the holes and welding them on their tops and sides should be sufficient to permanently plug the holes.

Looking good. Lets see the live rock and sand added so we can get the cycle going!
