I enjoy reading the forum even though my pool has been closed here in NJ. This morning the temperatures were at 43 degrees so the bad news is that there will be no swimming until next year. Good news is that I have all winter to educate myself on the TFP method. I feel pretty good about the method already.
Lately I have come across information on salt as a byproduct of liquid chlorine and there was a post back in 2013 from Chem Geek that stated that for every 10 ppm of FC in chlorination liquid there is around 8-9 ppm of salt added to the pool & when the chlorine gets used/consumed, there is another 8-9 ppm of salt added to the pool for a total of 17 ppm salt. This is easy to understand as it is basic math.
Further reading suggests that people have very high levels of salt in their pools. But how much is too high? . I fully understand that higher salt is better then higher CYA. A few questions:
Q: I have the TF-100 Test kit but do not remember reading about testing for salt. Can I order something to test for salt and if so how often should I be testing?
Q: At what levels does salt pose a potential problem for a vinyl liner swimming pool and what are the adverse effects if any?
Q: Does salt naturally disappear when the pool is closed for 8 months during the course of the year?
Q: Are there chemicals to reduce the salt content in swimming pools or is a drain-fill the only option just as if your CYA was too high?
I switched to the BBB method halfway during the year and removed the Frog Mineralizer and Bac Pacs. My CYA level stayed consistent at around 40. For about 2 months before the pool was closed I added around 2 ppm daily of liquid chlorine so my salt readings should not be too high. I kind of miss testing my pool water with the TF-100 (maybe because I really never liked chemistry or science in School) LOL
