Oh boy -- I am confusing people but learning a lot. The house CYA is zero. The pool was NOT filled this month. The pool has been in our family for 6-years and, I don't believe any water has been added or drained in all that time -- honestly it's hardly ever used. This month we will be draining and re-finishing. As far as the CYA test, I tested inside but not at night.
Because I decided the badly etched surface needed fixing I was flung/forced/dragged into learning about pools a mere 3-weeks ago. The good news -- the TA was 140 and pH 8.4 the first time I tested it so I feel I've made baby steps. Keep the advice coming -- I need all the help I can get!

Absolutely! You got it. Those tabs have stabilizer in them (beside chlorine), and that's exactly what's happening.Does this mean the in-line system is adding too much driving up the CYA?
Well, besides using something other than pucks (SWG or bleach), then periodically some water may have to be exchanged just to keep the CYA down to a manageable level. When you're away from home or can't add chlorine, that may be a final outcome. Later, you may want to look into a SWG (salt water generator) which creates chlorine from salt in the water and does the work for you. A SWG will not increase CYA like the in-line does with pucks/tabs.Can I -- the pool -- tolerate this if it's corrected occasionally?
