Newbie here- just stepped into the world of sand filtering this past weekend.
I'm sure most of this has been discussed in the past by others, so I'll be succinct. After initially running the pump for a couple of hours, the pressure gauge moved into the yellow zone. Figuring this was sand "silt" that had accumulated, I backwashed, and ran again. Again, after about two hours, it again popped back up into the yellow zone, so I backwashed again. Little by little, this 2 hours has stretched into longer periods of time before backwashing.
I know that everyone's pool situation is different, but if I'm having to backwash on a frequent basis like this, I'm just wondering how much this unit is going to save money for me, compared to my old cartridge filter system. I don't really feel great about leaving this unit on a timing system for fear of burning up the motor one night.
The water is crystal clear and the tests come out next to perfect, so I'm not dissing the results of the system.
BTW- I'm using a saltwater system too, 6400 gallon circular/round structure- all Intex.
