New member here. Wish I learned about BBB few weeks ago.
22000gal IGP, PebbleTec surfacing, cartridge filter, 8ft deep end.
Color was greenish/cloudy for greater part of a year. Got fed up and decided to shock the heck out of it after reading about breakpoint chlorination. Did a rough test at local pool store first: FC=1, pH=7.2, TA=100, CH=240, CYA=60, TDS=500. Not knowing about CYA side effects, decided to dump ten 1lb. dichlor bags I had sitting around. Reasoning at the time was since dichlor was close to pH neutral, might as well shock with that so I dont' have to mess with pH balance.
Chemical chart said 1lb/6700gal of dichlor results in 10ppm FC increase. So dumping ten bags shot my FC level to around 30+. After 2 days with pump running 24/7, pool was blue as can be, cystal clear everywhere. At 8ft deep, I could literally count individual pebbles on the surfacing. This is great!... or so I thought...
Ordered TF kit and arrives sometime this week. But pool store tests now read FC=5+, pH=7.2, TA=110, CH=375, TDS= 600, CYA=100. It's not until I learned about CYA sources that I started kicking myself Only consolation is that the pool loooks perfect, at least for now. For all I know, CYA is well above 100.
If I start using strictly bleach, will CYA at least slowly dissipate on its own given enough time?
