Is it unusual to get different results from different pool stores on water testing? I use a Taylor Pool Test Kit and what I get for test results (for FC and TC) is the same for one store (Leslie's) but not the same for another store (local Pool store). I tested the pool list AM and got a 5 on the CL and a 5 on the BR. Made two bottle samples and the local pool store said I had .3 on FC and 2.6 on TC. They say that the pool has ammonia in it which is eating up the chorine. I also used a test strip and it comes back with 0 FC. There is another difference with the CYA as well.
Quite frustrating. Any insights?
