I purchased my house at the beginning of the summer last year and my CYA was around 220. I did several partial drains and got it down to 50. Since it was at 50 last summer and i only use liquid bleach as my chlorine I have assumed it was still 50. I have only tested my FC a few times this year and have been adding the same amount of chlorine every night that I did last year and it has been staying crystal clear. This weekend I noticed it was a bit dull so I tested FC and it was 0 so I began a SLAM based on CYA of 50. I got my FC up to 20 and it was going away really fast during the bright hot day (95 - 99 degree in full sun). After the first night of SLAM i did a OCLT and had only lost 2ppm FC with no CC. After the second night of SLAM I did a OCLT and lost 0 FC. This did not seem right since I use so much FC during the day... I did a CYA test and it is now 0. I tested it again and it is indeed 0.
I currently have 2 socks full of CYA pellets floating in front of the skimmers...
This seems really strange to me. From what I have researched and read this seems really rare. I'm going to be testing very closely to see what happens. It may be time to use up these leftover chlorine pucks since I need CYA.
