H2O Res-Q® Conditioning Drops – 2 oz Long-Term Potable Water Storage Support

Product seems good. Customer service answered the phone and answered my questions. I called about the reagent kit and how I could not see the reaction to confirm it was working. They said it should be very light and hardly noticeable. I work with reagents occasionally and the point of them is to change color to confirm reaction presence. Consider modification to the test kit so customers can confirm it's working. No way to tell if it is sufficiently diluted. Customer service said not to add extra drops to try to see the color. Less is more in their words.

We have a large tank of water for emergency purposes, and we are assuming that the product will maintain its quality for years to come. It was easy to add to the water as we fill the tank.

Happy it arrived and shipping was less than other places for the same product.
