Background:
A month ago I replaced my liner, which was 10 years old, and ordered TF-100
refill kit which I use daily.
Three weeks later, after everything stabilized, I started looking at my pool results closely. Results were close, but I wanted some validation.
So one fine day I took four pool samples, put them in a cooler and off to satisfy my curiosity.
Two pool water testers, in a city of 900,000, one a franchise and the other a factory store.
One pool water tester, town of 85,000, independent. The other pool water tester, town of 40,000, independent. 100+ miles separating some of the testers.
Oh, I forgot to mention I am a retired engineer, with some time on my hands, which explains a lot of things.
These are the results of testing.
| TF – 100 | Ind # 1 | Ind # 2 | Factory | Franchise |
| | | | | |
FC | 2 | 0.3 | 1.84 | 1 | 2 |
CC | 0 | 0.9 | 0 | 1 | 0 |
PH | 7.8 | 7.6 | 8.2 | 7.8 | 7.8 |
TA | 120 | 100 | 140 | 120 | 150 |
CH | 190 | 180 | 150 | 280 | 225 |
CYA | 50 | 35 | 30 | 60 | 50 |
SALT | 3600 | 2300 | 3500 | 3100 | 3100 |
BORATE | 50 | | | | |
Independent # 2 didn’t want me to see results. Just told me what chemicals they were going to sell me to get my pool “right”
Independent # 1 said everything looks good except salt. Throw a couple of bags and all will be good.
Factory store really busy, handed me my results and said "here". That was it.
Franchise explained what was needed to get PH amd TA down and the need to increase the stabilizer.
I'm sticking with my TF-100 it's worked well for me over the years.
