I always have a fine layer of DE in my gunite pool (on steps and on bottom) even though the Polaris runs daily. I have replaced the spider gasket and the multiport valve and the DE filters (they are rectangular plates) -- all multiple times. Does anyone know how the DE is getting back into the pool?
For lack of a better idea, I am planning to replace my Sta-Rite S7D75 filter.
Appreciate any thoughts, guidance, etc.
BTW, had Leslie's and some other service people out but they are all clueless.
