I recently pressure washed my hayward cartridge filters (I realize now that I should not do that). When I vaccum the dirt from the pool, I can see particles of dirt returning to the pool. The filter pressure is fine. Do you think pressure washing could have caused this?
I have ordered new filters which should be here on Tuesday. 3 days ago, I added stabilizer. I heard it takes a week for it to register on my tests. Does that mean that I should wait at least a week before changing the filters so I dont lose the added stabilizer?
