If you're going to pump water from a sump below your tank to another sump in the mech room the 2nd sump will have to be higher than the first sump and have an overflow installed so water can flow back to the sump under the tank. I really have no clue what ScubaSteve is suggesting but attempting to match flow from two or more pumps is bad idea, not saying that's what he is in fact suggesting. Whatever you pump water to has to have dependent flow rate back, not independent.
