My pool has always been perfect and self sufficient. We live in So Florida. My pool is approx. 17,000 gal, salt system (haywood aquapure t15 cell) with a high efficient pump. solar heat and cover. Average temp 85-90.
I all started when I installed a new high efficient pump. After a few days I developed algae despite having acceptable chlorine readings. I assumed when was the pump ahas installed it was not programmed properly for the pool.. I simply changed it to run at 3000 rpm for 12 hrs. I shocked the pool set the chlorinator to 70% (above what I had normally set the system) and moved on. I then developed significant problems with algae due to low chorine levels. I ran the pump at 3000 rpm for 15 hrs day ). I called and conducted several tests with Haywood and the system seems to be passing the their test, however, the chlorinator system will run (produce amps) for example for 2 hrs and then shut off infinitely. Haywodd states this has never happened before . I had the main board replaced, nothing changed. Cleaned the cell (it was clean), no change Haywood also states since my stabilizer is not at 80 there system will not maintain the necessary chorine. i.e. its my fault.
Ok I started watching my stabilizer and borough it to 80 which it goes back down over a week . In all, I have added more stabilizer over the last 3 months than i have used in 3 years. It wili rise to 80 and then fall back to 30. Were not getting any rain, I am not adding water to the pool . I add the stabilizer thought a sox into the filter basket to a "new" filter in the pump and will not clean the pump filter for 5 days. Tries both powder and liquid stabilizer. Help!!! Why wont my pool hold stabilizer. Cannot find one shop in So Florida that can answer this.
