[rallen]

Have used this year Polaris 390 a lot LIKED IT BUT
now have a significant copper problem in my SALT pool
Only thing new this year was the switch to the POLARIS 390

There is no 390. There is a 380 and 3900. Neither has copper in them. Check your fill water.

Copper mostly comes from copper algaecide or from heat exchangers. How much copper do you have? Are you measuring it, or are you getting stains?
