I have been studying the BBB method since last fall and I finally got my new TFT testkit today!
Please help me out.
I did the CYA test 3 times to be as accurate as possible with these 61 year old eyes. I even had my son check results with me.
We both came up with about 20 actually less around 10-20.I have an old Bio-Guard CYA testkit which told me around 50+ for CYA.(this is an old kit)
and we also had a Bio-guard pool store check the CYA and they came up with 70..!?..( sorry I can't trust them).
My question and concern is: Is the new TFT test for CYA really accurate?
My other test results were:.Pool just opened the other day..Got some additions to make I know.
Should I believe the new TFT kit? I do not want to end up with High CYA if it's off.?
I really appreciate your help and guidance.
wishing you well, thanks,
