| it will be able to handle UP TO 600gph. if there are 2 then 1200gph. most external pumps are rated for much higher than 600gph, but if there are 2 drain the 1200gph pumps will work just fine. i have a GenX PCX 40 rated for 1190gph powering my 125 with dual corner overflows.
if you only have 1 overflow ... i switch to something internal like a Mag7.
