Newbie here from 112 degree Phoenix.
I have had a clorine pool and have been proud of the condition I kept it in.
Just had a topline SWG installed. They added 120lbs pool salt. The "purple stuff" and an algecide.
The problem is that I now have CYA at 300.
Any ideas on what caused this?
Is it dangerous?
What should I do?
Regards
Mark
