Prepping for my slam this weekend..
Added 1 gal of bleach yesterday after finding out my FC levels were around 1. Calculations show it went up to around 7 which coinsides with my OTO results of 5-10. Tested with an old DPD kit that only reads up to 3 and it was wayyyyyy darker than the top reading. My K-2006 will be here today so I can get more accurate results...
Prior to adding bleach my PH was about 7.6.. 45 After adding it remained the same so I added 28oz of MA to bring it down to 7.1-7.2 (light reds are a challenge to read). Tested about 60 min later and it was down to 7.1ish.
Im going to assume the CC was in the same range as FC because it didn't change colors.
Tested TA and its sitting around 190 but I know that will come down just trying to maintain a lower PH.. No worries..
My concern is my CYA. Tested half a dozen times and still see a black dot meaning its well below 30 and has never disappeared.
According to the CYA chart, if I start my slam with a low CYA, I will have to target an FC of 3 and Shock of 10... correct?
Should I try to gradually increase my CYA prior to the slam or just stick with a low target until I can get close to passing the OCLT?
