    First Time Test

    Just received and used my TF-100 test kit last night. CYA was low at 30 and cholorine was low at 1-2. I'm a little confused about free chlorine though. How to I figure out what that is again?

    Your initial test with the DPD powder (R-0870) and titrating agent (R-0871) five you your FC. You then add the R-0003 and if the color of the sample changes back to even the slightest pink, you count drops of R-0871 to turn it clear again. This gives you your CC.

    Your FC is your Free Chlorine, Use http://www.poolcalculator.com to find out how much bleach to add to bring it up to 4-6 ppm. Retest in an hour to ensure you have reached your target.
