I've had the TF-100 since late January this year, but I also just picked up a TF-Pro this month. I'm currently bringing my CH up to ~350 from the low point of 200. Everything was going well until I used the TF-Pro to test today, then I compared results between the two.
3/31: I started with CH 200 on 3/31, adding 8lbs calcium chloride and that brought me up to 250
4/12: I got 275 CH on another test 4/12 without adding any, that may have been my interpretation of the color change that day
4/14: 250 CH and added 8lbs calcium chloride
4/15: 300 CH
4/16: 8lbs calcium chloride
4/17: 325 CH
4/19 12PM: 325 CH, then 8lbs calcium chloride.
This all made sense from what I was seeing in PoolMath effects of adding, but today I switched over to the TF-Pro and got conflicting tests...
4/19 10PM *TF-100* CH 375 (15 drops) // *TF-Pro* CH 550 (22 drops).
I did them side by side to reduce the chances of interpretation. My testing thus far has been pretty predictable.
I've got my PoolMath logs posted but I haven't entered any data in for todays CH post addition since I got conflicting results between the two kits.
