Hi! I'm in Gilbert too... glad you found TFP! I can guarantee if you follow the methods here you will not only keep chlorine but your water will feel good & sparkle.. we bought our house here in feb 2020 and after we moved in realized how awful they kept the pool... I spent last summer repIacing equipment, and fixing the water (it was awful), that was when I decided I wanted a saltwater chlorine generator & that was the best thing we did living here... a lot of people in AZ live by the "must drain pool every year" mantra someone told me once it was bad having "old" water lol I almost spit my drink in their face laughing... we can certainly help you get control & stay in control First step: get good test kit Next stop using pucks & powder chlorine use liquid chlorine Pool Werx has good supply of HASA chlorine here. That's where I go to buy liquid chlorine, they don't try to sell me anything I don't want just ask me how im doing & how the pool is
