I am in Maryland. I am struggling to understand an issue with my filter that I started to have near the end of last swim season. The issue is that D.E. powder does not stick to my filter grids! I opened my pool last week and I have started from scratch twice using D.E. from two different manufacturers, first with a product bought from Leslies and then a product brought from WaterCrafsters. No difference. When I opened the filter tank I still see no coating on the grids.
Then today I noticed one thing. After the pump stops, white powdery water comes back to the pump (I can see it through the clear window) and goes slowly all the way back to the skimmer (I only have one skimmer). I don't remember I saw this when I had no problem with the pool. I don't know if these two are related.
I asked Leslie's and a local pool service store WaterCrafters and they didn't seem to know why DE wounld not stick to the grids either.
I don't want to run the filter without the grids properly coated with DE.
Anyone knows what is going on here? I am starting to get frustrated.
Any help is greatly appreciated.
