Your in the right spot! I would maybe go with 3/4" drain and 1/2" return for that size tank. Depending on what size pump your planning on using.

Btw there's bulkhead fittings at farm and fleet for smaller sizes if your having a hard time finding them.

another question i plan on draining my water into into another tank while i drill it and also putting my live rock fish and corals in it also but what do i do with the sand im hoping to only have my tank down for a few days and after put the rock sand and everything back into the tank and maybe doing a water change when i get it back together
