I have a 24ft round AG pool that is 12 years old. I have never had any trouble with it until about 2 years ago. I had problems keeping chlorine in the pool. Over the season I added a very large amount of chlorine, and didn't get a stable reading until the end of the season. Last year, my chlorine reading was high throughout the entire season! This year, I again am not seeing any chlorine readings. My calcium hardness was 295 on initial testing, and the water would only cloud up upon shocking.... it was a mess! I did a partial drain between 1/3 to 1/2 and refill. I cleaned my filter and recharged. The water looks crystal clear and beautiful! BUT, I still cannot get a free chlorine reading. Here are my latest stats:
19,500 gal AG Pool
Sat Idx: -0.3
Tot Chl: 0.4
Free Chl: 0
Tot Alk: 140
Adj Tot Alk: 134
Tot Hard: 194
I added 1/4 lb. of pH, 2 lb Stabilizer, 1 bag shock, 3 oz algecide........ No chlorine reading the next day
Added 1 gal clorox.... No reading next day
Added 2 gal clorox....No reading
Added 1 bag shock and 2 gal clorox.....Nothing!
I am beyond frustrated! Why would my readings all be normal, but still not have a chlorine reading? In all my years of pool maintenance, my routine usually consisted of super chlorinating at startup, and shocking when needed...
Help! and Thank you!
