I bought a used 235ish gallon tank with already drilled corner overflows. Each overflow has a 2.5" and a 1.5" hole. I'm assuming the 1.5" holes are/should be returns and the 2.5" should be the drains. It will be no more than a 7' head and I would like to have atleast 10x turnover so assuming i setup the plumbing correctly all I need to do is have a pump rated at 2400ish-gph @ 7' and I will have a working tank. Also any advice/comments on Reeflo pumps. I've been pleased with what I've been reading so far.
Thanks!
