Hi out there! My first post...

I'm basically bringing the pool back to life after the winter. It's light green right now, and sorry don't have any #'s for the chemicals at this time. Working on getting it shocked, but with the way the filters are acting...

My DE filters are clogging within a couple hrs after I have disassembled and cleaned them with the hose. At this point, even after a back-flush, it clogs within 30 min or so.

Usually in the past, I have only needed to back-flush every couple weeks or so. (regardless of how nice or cloudy the water was)

The filters are a couple years old, and seem to clean up real nice with the hose.

It's an older Pentair system with 8 grids (7 + 1 small)

Pool is around 20' x 40' (shaped like mr peanut), & ~40k gallons w/attached spa


Also, I need a new timer, anybody have a good recommendation?

Thx!
