First time posting, but been relying on your expertise for a while...
I am at the point where it seems my CYA levels are 200+ - according to the "black dot disappearing" test using a FAS-DPD kit.
In addition to outrageous water prices, Los Angeles is beginning to put a chokehold on filling pools and such. Consquently I thought I'd look into one of these "reverse osmosis" pool services.
Do any exist that service Los Angeles, specifically the San Fernando Valley?
Thanks in advance!
