So bought this house in December that has 33,000 gallon pool with Aqua Rite system matched with Turbo T-CELL-15. The Aqua Rite control box on the wall from 2013 according to receipt. If I go by receipts kept I can only assume the T-Cell is from September of 2007. I live in Fort Worth. The previous owner was running the pool pump 365 a year for 12 hours a day and 2 hours of that was running sweeper on booster pump. The SWG was set to 70% output. In my mind 12 hours a day seemed excessive and might have explained his electric bills. I talked to some pool owner friends and they said in the winter they would never run for more than 4 hours a day. Not know how much liquid my pump could turn over in an hour I cut the run time in half. 6 hours a day and 1 hour on the sweeper.
The display on the Aqua Rite has shown 2700 since I moved in which I knew to be below ideal from Hayward manual. When the pump was running 12 hours a day the FC was consistently 12. After turning it down to 6 hours it was around 7 at 70% output. Previous owner advised I clean the filter every 3 months and inspect and clean the SWG at the same time. So end of March I decided to clean filter and inspect SWG. The SWG appeared to have 1 or 2 'fins' with some build up. I cleaned with acid and water and replaced.
At this time the FC started to drop slowly till about 3 and it was steady for a few days. The next time I tested 3 days later it was 0. I turned up the output to 100% and Super Chloro and both failed to raise the level. I did the diagnostic today and the Instant Salt check showed 0. The main screen still displayed 2700. I re-cleaned the SWG today and placed back on and still 0 salt. I took water to pool store and it tested at 3200 actually.
I am assuming the cell itself is having a problem. I am a DIY guy with not a lot of extra cash to throw around so does it sound like I need to buy a new T CELL 15 or is it possible something with the control box is messed up? I would really love some opinions before I spend a bunch of money on possibly the wrong component.
In the meantime I am back to using bleach to chlorinate to a 4. TA and PH are a tad high currently.
