27,000 gal. 75F.
Calc 1210 oz (10 jugs) 8.25% bleach would get me to fc 30. Where I planned to get more in morning to maintain.
Tested 2 hrs after application. fc .5 (if that). tc 20 (didnt scale test to read 30).
Pool is a swamp, looking better around steps. Im now assuming this fc consumption 20/30 in 2 hours during night is possible with high contaminate.
Contemplating how to proceed. Was going to identify/quantify shock on hand. Wondering what product I should try to continue the process with in the morning.
