Its time to close my AG intex 32'x16'x52" 14,365 gal. pool. My ALK readings is and have been consistent at 140 , my pH is 8.0 and has been consistently so. My CYA is 70 my FC is currently 4.8. My concern: Can i close my pool with these readings? My water is crystal clear and has been since I started using the BBB pool care. I hate the thought of trying to fix something that does not appear broke. But, honestly....I just don't really know. This is my first year of owning a pool. Any help and/or advice would be greatly appreciated. Cordially YvonneSEU
