Evreything started when we had the pool partially emptied to remove a rust stain just below the light. It has never worked since then. After filling up the pool with water we started to see the no flow message. A technician came over and replaced the switch, I believe, a screw type on the top of the cell. We were relieved because it started to work without the "no flow" message. Soon we realized that it was not producing any chlorine even without the chlorinator off message. First I thought it was the weather, winter in Norcal, then not running enough hours. I have been putting about 11oz. of chlorinating bleach? (not sure the name, the gallons we buy at Home Depot) since then. I have noticed, lately, the PH has been higher than before. These last month it's been requiring almost he double amount of muriatic acid to bring it down the ph than before. I do a weekly test on Saturdays morning, I check for chlorine & ph. Drop the required acid first thing on morning and put the chlorine in at night, after we leave the pool. Now I'm thinking if a should put some CYA, since we have never put it back after refilling it last year.
My other doubt is if this switch replaced can have a volt or some spicification in it that would be for a cell used in a smaller pool.
The cell is cleanned, filter, everything has been maintained as required and well. What are we missing? What can I do in order to have it start to produce chlorine? Salt is good too! What else is needed to be checked?
I read the other posts but even if we have the same problems I don't have some of the wrong readings, or something else. We have it working at 60%, we tried 70% when it still worked well and it was perfect to bring the chlorine up in about 2 days, but after that the levels were to high, so we decided to keep it at the initial settings of 60% for the pool and 3% for the spa. Would I screw up the chemics if I add CYA? Thank you
