Let me know if you see any flaws. My mentor "Mark" (Flyingarmy) is on vacation. The drain is 1.25 (that is what fit the bulkhead that came with the tank) and the return is 1 inch. There will be a loc line connector on the end of the return. On the drain I drilled a small hole in the cap and am also drilling a hole a little below the water line on the drain. Let me know if this looks / sounds correct as I am new to building these. Thanks.
