We have a 2 month old pool, and I did the HTH home test.
The HTH home tester claims that my alkalinity is too low (70) and when I went to a pool shop ( they sell Bioguard)
they tested the pool water and stated that TA is too high (165)??
Just want to add... I read that you are suppose to use the plastic lids when testing as mixing with your hands ( or the sweat on it) can change the reading... The pool guy used his palm to block the tube when shaking the test tubes ... could that have influenced the TA reading as well?
My question is... which test results should I trust the pool shop (bio guard) that says its to high
HTH home kit that says its too low?
