Great purchase!
This is the easiest way to check our pool water! Great quality and works very well! In seconds we can tell if we need to add chlorine or PH (up or down). Must less expensive than the test strips!

Keep pool healthy at a lower cost
Keep your pool healthy and safe to swim in at a much lower cost than pool supply storefronts. Checked these against the original kit that I had and they provided the same results. I was concerned that they may not be accurate as the kit that came with the pool. These produced the same results.

Phenol doesn’t work
Apparently, the phenol is very low concentration. I add 5 drops and test tube is almost clear. Besides the bottle is so small that it doesn’t fit my test box.Am purchasing something else. Waste of $$.
