Here are my numbers on my first testing session with tf-100 kit With the stirplate option

[jbpoolz]

PH 7.3
CL 5
FC was 8 Drops Do I add this to CL to get 13?
CC 1.5
TC 9.5 or 19.5 if I add cl and fc together
CH 275
TA 70
CA 80

Also do you guys recommend only liquid chlorine or 3" tablets

Thanks

The CL test (yellow drops) and the FC and CC test (drops and powder)are totally seperate. The yellow OTO test isnt all that accurate so stick with the FAS-DPD. If that test took 8 drops to go from pink to clear, then your FC is 4ppm. (Assuming you were using a 10ml water sample)

If your CYA (white cloudy tube with the dot on the bottom) is 80ppm then you dont want any more CYA in the water. No more tablets (which have CYA), stick with liquid chlorine. And get some in there fast cause its too low with a CYA of 80ppm.

Thank you I will run another test and see how it comes out. I will be grabbing the liquid chlorine tomorrow. Thanks for the info on the tabs I will just go with liquid now.

Thats better but your FC is still below minimum. Make sure you always follow this chart:

The Free Chlorine and Cyanuric Acid Relationship

Managing your cyanuric acid and Free Chlorine levels is key to stabilizing your pool. Learn how these two items affect each other.

You can also ignore the reporting and test for TC as its just a math equation of FC and CC = TC.

One other adcice for the future would be to list the CYA as such instead of CA, as that can get confused with calcium.
