Hi all. I've discovered a white powder in the pool coming from my returns. It looks almost like soap flakes or snow and disolves into a fine white powder when touched. Maybe a cup or 2 total.The pool was just converted to SWG, is 28k and ph and FC are normal, CH is still high at 700 and CYA is 75-80. Also the solar started running only a week or so ago.
I'll try to upload the photos I took later. Any ideas?
