I received my TF-100 kit and completed my first round of tests. Results:
FC - 6
CC - 0
PH- 7.5
TA - 100
CH - 800
CYA - 90-100
With the exception of CH, the results are pretty much what I expected. I performed the 10 ml CH test and stopped after 20 drops thinking I did something wrong. The second test took me to 32 drops before the sample turned from pink to blue. Third test showed the same results. I did not notice a "fading endpoint" as described in the Pool School section. I recently had my water tested three times at two different pool stores. Results were between 260-280. I know not to trust pools store tests, but the variance between my numbers and the pool stores' is significant. I followed the instructions included with the kit and at the Pool School closely so I'm perplexed. I recently installed a SWG and have been running it the last week. Prior to that for the two year life of the pool, my primary source of chlorine was pucks and powder shock, which explains my high level of CYA.
The CYA test was the hardest to read. I did the test with a full sample and ended up having to dilute. I would like to get a second set of eyes on the CYA test. My wife will be home tonight...how long can is the combined sample good for?
Water is clear with no signs of algae. I do have scaling at the waterline.
Any tips would be appreciated.
Mike.
