so, i installed my bulkheads for my sump, got it up and running then realized i had made a ridiculous mistake. for some reason, all my "research" had led
me to believe i did not need an overflow box, so i plumbed two 3/4" returns and a simple 1" drain in the middle, at the top of the tank. rigged it all up, looked beautiful. turned on the pump, no leaks! but then, i realized that my drain wasn't draining so well. thinking about it, it's obviously because there is not enough water pressure to force it down. whoops. can't believe i didn't think this out better before hand. would it be pointless to add another drain to compensate? should i plug the drain i have, drain the tank, drill another hole in the bottom and install a stand pipe? for the time being i've got one of the returns running with half of my pump pressure running back into the sump, and i threw a powerhead in to add some flow. arggh.
