Hi Ph powder does not desolve
Only issue is the high Ph mix does not desolve easily, sinks to the bottom on the jar and becomes a crusted mess. Ph tester only reads 7.5 not expected 9.0

Keep that meter calibrated!
These powders do the trick and keep my pH meter accurately calibrated. This in turn saves me trips to the store to get my hot tub water tested and I love a product that saves me time and money. Oh, did I mention this stuff is cheap! I will continue to buy until my hot tub wears out!
