Well for the bath tub i turned into a pond i need to reseal it up. I was thinking of installing a wet/dry on it. It has 2 holes, One on the bottom and one towards the top. I was thinking of leaving a hole in the bottom to drain to the sump and have a return at the top hole. I have a pond pump the moves 240gph and i wanted to know wat size hole i should have to get water to the sump w/o over flowing. Wat size hole should i have???

i think gravity would have more water going through the hole than the pump can push back into the tub.
