Review on 80 Pieces Water Test Litmus Strips Litmus ph Paper Soil Acidity Meter Liquid pH Tester 1-14 by Mateusz Sowa ᠌

The description says that it is suitable for the pool. actually doesn't fit. conducted an experiment. in the pool shows a neutral environment. leaned against a sour apple, the paper barely turned yellow, completely unsuitable for testing water for domestic needs. by the time when it already shows deviations from the norm, it will be clear to taste! maybe good for chemical experiments. but not suitable for the pool, the description is a hoax.
