I'm at wits end on this one. I added salt to "soften" my water a bit (my hardness is off the charts, out of the tap it's 400+) and am currently holding steady around 2000ppm based on what my test kit is telling me (K2006 or something like that with the salt add on.)
I CAN NOT get my cholorine levels down. I haven't added any pucks or liquid in 2 weeks, and my TC and FC are still way up above 10.
Could this possibly be caused by the salt additive messing with the readings? I've tested cholorine with both the big test kit, 2 different small test kits, and strips, and I get the same reading.
CYA is in the 40 range as I just refilled the pool a couple weeks ago. Maybe that's the issue? But, I would think the lower CYA would cause the chlorine to burn off? PH is 7.4 so that's within range.
Only thing I can think is that the pool itself is generating cholorine from the salt?
Not that I'm really complaining....the water is crystal clear, feels good to swim in, and no flora growth! I just don't want a surprise one day to find the TC and FC at zero after being away for a couple days and have a mess on my hands!!
