I have been using the TFP Method since I bought my 1975 home 2 years ago. I have never had a single problem just a sparkling clear pool. Now for my problem, towards the end of last season I started to notice a salty taste to the water but didn't think much of it. Fast forward to this season and I still notice a salty taste. I have never put salt in my pool and it never had any taste till end of last year. I use the TFP testing kit so I took a sample to the local pool store where I buy my %10 Liquid Chlorine and Acid and had them test for salt content, came back at 2600ppm. How did salt enter my pool to that level in 2 years? when I moved in I drained and refilled my pool so there is no way it was because the previous owner put salt in. Oh and there is no SWG or ever was.
My number using TFP Testing Kit
2600 Salt (at Pool Store using computer tester)
Thanks for the help in advance I read this forum every day even though I have never had an issue.
