Hi, I just bought TF100 test kit and confused with results. The water looks very clean and I do chlorine does not smell that bad, so I wondering what's going.
I just bought a house and pool maintenance was new to me. First 4 weeks, I would go every 3-4 days to a local pool store for tests and every time they would say my FC is 5ppm and said to keep it that way. All other parameters were okay. They told me to shock it once a week and keep adding tablets to chlorination which I did. Now when I got TF100 and measured FC, i got 38ppm two days ago and just tested it again and got 41ppm. I am bit confused as well because the laminated instruction in the kit says to multiple number of drops by 0.05 but the examples says if you do 14 drops multiple it by 0.5 which means it would be 7ppm. So is it 0.05 or 0.5?
Here is my test results:
2 days ago:
FC 38ppm ( 76 drops)
FC 41ppm ( 82 drops)
Now i wonder if my pool is even safe to swim. Looks like a crazy level for FC, no?
