oky i just setup my sump today i have a hurricane 600 overflow rated at 600 gph and i have a mag 7 pump rated at 700 gph going upwards about 3 feet which should take it down to around 500 or so gph... this is my problem my overflow isnt taking out enough water its going through alot slower then my pump is pumping it back....... i have a ballvalve on my return pump and i have it almost completly closed slightly open to get the water matched up wiht my overflow. any ideas on whats wrong, the u tube "siphon tube" doesnt have any airbubles in it.. but yet the overflow just doesnt cut it... from the bottom of the overflow i have 2 90 degree andgles that connect it to the bulkhead on top of the sump this is the only way i could hook it up.... i know this is confusing any ideas would be great thank you very very much....
