I just performed a full chemical test using my new TF-100 kit. I had drained 1/4+ of my pool a couple of weeks ago attempting to lower my CYA. I drained an additional 1/4+ a couple of days ago. Today my CYA registered 45. Good. However my CH remains high at 850! I tested my pool-fill water and it registered 500 so I'm fighting a losing battle here I think. I watched a short video posted by a member showing an alternate method of adding regents but I'm not sure the method described would result in a significant change. Do I just have to live with high CH? What damage would I begin to notice? EDIT: The pool is about 5 years old and has been monitored by a "pool boy" for the last 4 years.
Todays results:
CC 1.5
FC 4.5
PH 8.2 (Will add 2 cups of muriatic acid in the morning when the pump starts)
CH 850
TA 250 (I'm going to try the low PH/aeration method to lower TA over the next few weeks)
