We haven't ordered our test kit yet. It was just filled. The pool store tested it . They are who said we needed 12 lbs of shock. It is 12,000 gallons. The free chlorine is 0. Total chlorine 0. PH 8.8 total alkalinity 125 total hardness 46 . They had us add 3.25 lbs of Lo N SLO and bottle of algecide.They say we need 12 lbs shock. I want to order a test kit and get the BBB method going. Where do I start while I wait on my kit ?
12 lbs of dichlor will raise your CYA by 56 & your FC by 61. 61 ppm FC in an unstabilized pool will definitely damage your liner. Cal-hypo would be even worse.
I hope you didn't add that much. You only need 1.5 large jugs of bleach to get to shock level.
