it all depends on what you want your turn over rate to be. the only restricting factor would be the size of the overflow or how much water your overflow can move out of the tank.

So I should be ok with a pump that turns over 1600 gph and is adjustable? The sump is 80 gallons/6 feet long, the tank has 2 overflows with half inch plumbing.

Are you sure its half inch plumbing? That would be some of the smallest ive seen on a tank bigger than 50g. Unless you are running a herbie style full siphon you arent going to get much flow through that. Id give figures but I couldnt find any info on smaller than 3/4" which was about 200gph unless running full siphon was closer to 400 gph

do you know what you want your turn over rate to be? cause that is the first question you need to answer. once you get that you can look up all the info you will need to accomplish that. then you drill the return line from the sump to allow for that and drill the drain holes large enough to keep up with that flow.

I'm looking for 5x an hour, so 1450 gallons an hour for a 290 gallon system gets me 5x an hour,I can drill bigger bulkheads if I need to.
