I am following the TFP guidelines this year as far as chlorine levels directly correlating to my CYA levels. Everything is balanced perfectly at the moment as follows:
pH 7.6
FC 7.0
CC 0.0
TA 110
CYA 45-50 (my best guess, it's so subjective this thing "when the black dot disappears")
CALCIUM 210
I test daily and I use liquid chlorine to keep my free chlorine round about 7ppm. It seems that I need to add 1 quart of liquid chlorine (12.5%) every day for my 21,000 gallon pool. Usually I test when I get home from work and the FC reads between 5.2-5.6 or thereabouts everyday so 1 quart usually gets it to 7 or just above. I usually add the chlorine around 7-8pm and let the pool run for a couple of hours more before I shut it off for the night. Then I turn it back on around 8am.
Once a week or less I need to add some muriatic acid (about 16oz split up into two doses) to keep the pH in check. After a few weeks I might add a little baking soda (2-3lbs) to bump the TA back up, and then repeat.
So my question is, does this sound about right? Keeping the chlorine that high each and every day? I am not damaging my pool liner with this consistent higher levels of chlorine? I read that CYA stablizes that specific amount of chlorine so that it shouldn't do any damage to anything. I just want to make sure I am good and hear from some of you who have been doing it this way for years.
I am using a Taylor K-2006C test kit for all my testing.
