I have an 33000 gal inground vinyl liner pool that was converted to a salt water system approximately 2 years ago. Everything worked great until this spring. After uncovering the pool, I've shocked it and added algecide several times and each time it would begin to clear up and then get cloudy again. I began to suspect that the cell needed cleaning, so I did that just yesterday. But, before I cleaned the cell I pressed the test button on the control panel for the chlorine generator (Polaris AutoClear) and there were three status codes in this order 53 - 22 - 90. The only code that I ever paid attention to is the 90 which indicates that the salt level is good. After cleaning the cell the codes read 54 - 23 - 90. Does anyone know what the first two codes are for and what they mean?
