Hey folks,
I just picked up a used Custom 75G Drilled tank. The person had a bottom to top overflow with a weir, single 1" drain and 3/4" return inside the overflow. It was a dirty tank and when I got it home and started cleaning I noticed it had 2 more holes drilled in the bottom for 3/4" sized bulk heads and these are outside the overflow. My question is 2 fold. I would like to put the main drain, and the secondary durso inside the overflow and use one of the outside holes for the emergency drain, and the other for the return. Question 1 is it ok for the Durso and Emergency drain to be 3/4 or do they need to be drilled out to 1"? Question 2 Is it ok for the emergency drain to be outside the overflow? In my mind the Emergency drain could be anywhere in the tank as its just there to keep it from overfilling. Up until now all my tanks have been AIO so I am new to the remote sump thing.
