Not sure if I only have a highly alkaline water ionizer but even the acidic part isn't the color I wanted. As you can see from the photo they are all blue and have not discolored at all. The packaging/bottle of this product appears to be used and/or old. See photo, does not serve the intended purpose. It was recommended by the person who installed my machine. And he suggests checking the alkalinity and acidity of the water once every blue moon. Well, once in blue it should be too. Shipping from Florida to North Carolina and back to Florida took so long. I'm on the west coast so I have no idea why? It could also be the fault of the courier. I will try to return it and contact the seller. Let's just hope for the best!
