I am confused. I have been following the BBB method for about 2 years now with great results. My water is crystal clear. I have been maintaining shock level for about a week or so and have not lost any FC overnight. However, I am still consuming a lot of chlorine throughout the day. I have read that 3-4 ppm of loss is normal. I have started with 7-8 ppm in the morning and by 7:00 PM or so I will have 0 for the past 2 days.
If anyone can shed any light on this it would be greatly appreciated. My current numbers are listed below. BTW, my CYA test can't be accurate because a month ago it tested around 50 and I have not drained any water. I ordered refills and something has to be wrong. Thanks as always.
FC - 0 (was 7.5 this morning)
CC - 0
PH - 7.8
TA - 100
CH - 80
CYA - 0 (with new refill, tested at 50 a month ago)
