SICCE SYNCRA pump
I need help figuring out which model of Syncra pump I have to use in my future sump.PVC pipe going to be 4' long from sump to the tank.I'm thinking of 2 models:
SICCE SYNCRA 2.0 PUMP 568GPH
SICCE SYNCRA 3.0 PUMP 714GPH
I have Life Reef overflow box flow rates up to 600 gph.
My return is 4' high so has to loose sam's gph
Are this pumps are good or just standart pumps
Let me know your recommendation.Thanks
