I've read several other threads regarding sand filters, replacing sand, etc. I have replaced the sand 2 yrs ago, but for some reason this year the filter does not seems to be clearing the water much at all. I have used a garden hose with spray nozzle to clean the sand by simply moving the nozzle around inside of the filter (top to bottom); then backwashing it out. It seems like the filter is just not picking up fine matter. This is now the 3rd time this season so far where the water has become what I call 'dirt cloudy'. I treat the water with a Fall Out type product. After the treatment, a ton of matter is on the pool floor that I vacuum to waste.
So, my question is ....is there anything I can do (or not do) to retain the crystal clear water I have after the Fall Out treatment? I know about using DE powder with sand...although I also hear on some fronts its not recommended as the sand will definately clump together. HELP Please!!
