I am consistenly reading 450ppm CH with the TF-100 with 3 samples. Ran it to Leslies to get data logged for resurfacing warranty and they read 250ppm. I am new to the TF-100, but have been very religous about following directions and have read the expanded directions on the forum.
Could I be doing something wrong?
Should I discount the reading from Leslies?
TF-100 / Leslies
FC 1 / 2
pH 7.6 / 7.6
TA 90 / 100
CH 450 / 250
CYA 40 / 60
They said my phosphates were high at 1500 but I already read about that scam oon here so I smiles and thanks him for the test.
