About 4 weeks into the BBB method. Just tested the water. FC at 2.5. CYA at 70. FC dropped from 6.5 to 2.5 in just 6 days. pH at 7.5. Using the CYA/FC table, I would need to bring my FC levels up to 8, so using the Pool Calculator, would need to add 275 oz or almost 1.5 jugs of bleach.
(1) Does this sound right? Should I be alarmed by the amount of FC drop in 6 days? Since I travel a lot, it is tough for me to test daily for FC, so will need to test every 6-7 days. Is this testing rhythm ok? Should I run all the TF tests weekly, or just a few?
(2) At 1.5-2 jugs (182oz) a week, is bleach still a cheaper chlorine option than chlorine pucks?
(3) How do I know when to "shock" the pool, or bring FC up to shock levels?
Thanks for the help....
