First a little history, I had to put in a new liner last fall refilled with water balanced pool added salt for new chlorine genrator.and closed all within a week. This spring I opened pool and water was clear I added dichlor to get chlorine level to shock level, added algaecide, metal out product, a clarifier, and added borax. Water is crytstal clear at this point. I also added a circupool si60 chorine generator this spring. I waited for chlorine level to drop before turning on chlorine generator. Chlorine dropped to 2ppm so I turned it on to 25% and chlorine level is increasing, pool not being used yet. Salt is at 3500ppm.
My test results with the TF-100 are in question. I have not added any cyanuric acid aside from the dichlor I added this spring. The TF-100 test shows my CYA at 80ppm and I also have an older color Q its showing 40ppm. All other tests with the TF-100 I assumed were accurate.
Took a sample to pool store because I couldn't find my borate test strips and wanted to check CYA with there test. There results:
The chlorine and CYA are not matching what the TF-100 test is showing.
I thought I bought new reagents last spring and thought they were good for 18 months, so should get me through this summer. I also found my borate strips along with the colorQ tester and some other 6 way test strips. I quit using colorQ because of inaccuracy and bought the TF-100.
Anyway tested with the color Q and 6way test strips.
6 way test strips match pool store results. Color Q not so much, thats why I don't use it.
Are my reagents bad for chlorine and CYA? I've never compared results to a pool store before. I thought it was odd that the 6way strip matched pool store.
Thanks for any advice.
