Since I installed my SWG I have small white particles that are accumilating in my spa and pool. They look like a white gel or soft flake substance. They are not floating freely but settle to bottom of step or spa and accumilate in a pile. I dont see them in my main pool possibly due to the floor cleaner.. Any ideas on this on what this might be. I took a sample top Leslie pool and they said it could be the saly is removing the calcium at the water line..
