Could you kindly advise me on how to cost-effectively maintain my plaster pool (free form, with a spa) that is never used for swimming?
We are in San Diego and the pool receives lots of direct sunlight. We keep CYA at 50 PPM, and borax at 50 PPM.
Local temperature mostly around 40's to 70's and can go to 80's and 90's at times.
I wonder if I can get away with lower-than-typical level of chlorine and filter pump run time?
Thank you so much!
