Hi all,
I was recently told by my pool store that I have a high Chlorine Demand, and they recommended spending hundreds of dollars on burn out. I had already done some research on your site and I knew I had to switch to TFP methods. So, to lower my CYA of 140, I did a partial drain. Here were my readings before I started the SLAM.
FC - .4
CC - 1.0
PH - 7.8
TA - 160
CYA - 60
My water has been crystal blue all along.
I knew I had to get my PH and TA down, so I added 2L of Muriatic Acid, then aerated and my PH came up to 7.2, and my TA was 140. I then started adding bleach. This started on Sep 4. I tested using my T2006 at least 4-5 times per day, and made additions to get it up to SLAM level. This has been going on for 4 days now, and I have gone through 50L of 10.8% chlorinating liquid and still can't pass the overnight test. My FC drops by a range of 5-8.5ppm overnight. This morning when I tested before the sun hit the pool I was at 14.0FC and .5CC. Last night when I tested before going to bed the FC was 22.5. My water is crystal blue, and there is no debris in the pool. I have used my Dolphin to vacuum the pool daily and have sprayed the Dolphins filters and my cartridge filter too. I don't know if I should continue - as the pool will be shut down for the winter in a week or so, and I feel like the SLAM isn't helping my chlorine demand. Do I keep going or is there something else I should be trying?
