Experts, I am back after draining and refilling my pool to lower the CYA.
Here is a link to the last thread where I was advised to drain & refill again. Last thread
So, Yesterday, I finally finished draining and refilling the pool. Ran the tests and here are my results (before any chemical addition):
pH - 7.6
Free chlorine - 2 ppm
Combined chlorine - Absent (however, if I let the solution sit for a while, around 2-4 minutes, the solution turned slightly pink. With 1-drop, I was able to change the solution to colorless. So, is CC absent or is it 1 ppm)?
Total Alkalinity - 50 ppm
Cyanuric Acid - Less than 30 ppm (if I have to guess, it was about 20 ppm)
Calcium hardness - 90 ppm as Calcium carbonate
Since, FC was 2 ppm, I added approximately 62 oz of 6% bleach (based on pool calculator) to bring FC to 5 ppm. After 40 minutes, when I tested, FC was at 5.5 ppm, so I am guessing my pool is close to 9500 Gallons.
I also did OCLT. This morning (at 6 AM, before sun hitting the pool), FC was 4.5 ppm (night time FC was 5.5 ppm). Once again, CC was absent, however, after 2-4 minutes, the solution turned slightly pink.
Where do I go from here? I know that I need to raise CYA (to 30-50), total alkalinity and Calcium hardness. I dont have any chemicals, except liquid bleach. I am thinking that I should go with BBB method (if feasible). Can someone hold the hand of this totalnoob and guide me.
Thanks a lot.
