Just had my pool resurfaced. For the first two weeks, I relied on Leslie's and another local pool store for pool tests until I got my TF-100.
Did my first test today. I've got a SWG (Autopilot)
FC=17
CC=2
PH=7.5
CH=600
TA=80
CYA=30
The Leslie's results were very, very close to the TF-100 results except for CH. Leslie's was consistently in the 200-250 range. I did the CH hardness test three times (first time I didn't use the speed stir because the TF-100 instructions didn't indicate that was necessary but I see on the forums that it should be mixed until the water turns blue). Each time, I was in the 24-26 drop range.
Pool water is crystal clear and not cloudy. I've added CYA via the sock method but I'm puzzled at why there's such a variance (3x)? I'm not convinced I'm doing the test correctly.
