Did I damage my new Spa?
400gallon acrylic hot tub
After 4 weeks of using Dichlor (2oz twice a week), I got into a chlorine lock situation, with CYA build up. (FC .14, TC 7.25, CYA 83). (pH 7.8, TA 82) When I added additional Dichlor, the readings would come back at zero. Leslies did a water test (see attached) and informed me to add 6.9oz of Clor Bright (Dichlor-S-Trianzinetrione) granules to break to lock and shock the 400 gallon hot tub, making sure the cover was off and the jets were on for 1 hr.
I waited 24hrs and the chlorine levels were still through the roof, maxing out my test strips. You could smell the chlorine across the yard. Could this super high level of chlorine have damaged the hot tub components?
I was then advised to drian a few inches of water and fill it with fresh which I did ( drained 6" probably 80-100 gallon. The Chlorine was still around 8-10ppm.
Any feedback or thoughts would be greatly appreciated!
