16" cube ideas

ok now what kind of pump should i be looking at?

one of my suppliers carrys little giant pump, and being that we spend around $1m with them every year, i can get a good price on these


now basicly what i am thinking is that i wont need more then 500gph to move water from the sump to the tank

but could be wront there, would it be better to go 750gph or even 1000gph?
