It's time to change my pump and DE filter. I am planing to purchase a 2 speed, 1 1/2HP, Full rated, WhisperFlo (Model WFDS-6). I am confused over choosing which filter to purchase. Which is a more preferred and better filter for my environment. There are no trees or gardening around the swimming pool. But the pump and the filter are exposed to the harsh SoCal sun. And I also have a solar heating system with 2" PVC pipes in and out.
following are my choices:
1) Quad D.E. 60 - W/ an added Back wash valve
2) FNSP60 - W/ an added Back wash valve
3) SMBW 4060
I would appreciate help from this board. Thks
