I have a Pantera P20 High rate sand filter. It says to use sand #20. The pool store said they don't sell sand anymore they gave me Natural Rock for filtration by distinction.
- Problem I can not get my pool water clear.
- I have new sand or rock- I have clean the filter made sure the plastic inside is not broke, have my water test (they say chemical good). The only thing that's clears the water is if I shut down the sand filter for a few days
- I've notice if I shut my sand filter 2-3 days then my pool water goes crystal clear
- Do I need I new Sand Filter?
