About 8 months ago I noticed the light ring turning a dark color. Its a PENTAIR intellibrite 5G LED, the light engine burned out, when I took it out of the pool the ring was a dark gray and copper color. So I took a water sample to the pool store, they checked it and said the chemicals were fine, she then did a salt test and it was 2000 ppm, the pool is not salt water, and the only way to fix is to drain out a lot of water and refill with fresh water to get the salt ppm down. The pool was put in in 1989 had it resurfaced in 2013 and never had this problem until 8 months ago. I have a pool company come once a week 12 months a year. Can anyone tell me what my problem is and how I can fix it before I put the light back in so it wont occur again. And how to clean the ring. Thanks
