I have just recently switched to the BBB method. My water is beautiful - crystal clear. I live in central Indiana. We have had tons of rain and hot weather so far this season.
I have been testing with the k-2006 religiously. I know my TA is on the high side. I'm planning on using the advice on this forum to lower it.
Despite my beautiful water, I have been losing chlorine (never below 2.0) like crazy. I did the overnight test last night and went from 30.0 to 16.0 FC. I know that having high TA can affect chlorine efficiency, but can it cause FC to drop that much in such a short period of time? Or, am I fighting algae?
FC - 16.0
CC - .5
pH - 7.3
TA - 160
CH - 200
CYA - 80
