Review: Test Using a Room Temperature Water Samples - It works terrific. Reduced hardness from 250 to 100 in 14 hours. I did not flip it over yet. My Taylor test kit book said when testing for hardness use water between 60 and 90 degrees. I remember from high school chemistry that heat can be a catalyst when chemicals are combined. Based on that and what the Taylor people say I conclude that 102 degree spa water is probably too hot to produce accurate test results. So I used before and after glasses of hot tub water allowed to cool down to room temperature. I am 100% happy with my purchase.
Review: Great for hard water - Shipping was fast and the product is exactly what we need for the hard water in our hot tub. I will continue to order this product

### ⭐⭐⭐⭐⭐ Great for hard water
*by A***A on January 30, 2026*

Shipping was fast and the product is exactly what we need for the hard water in our hot tub. I will continue to order this product

### ⭐ It arrived wet
*by L***R on April 18, 2023*

I bought this twice. The first one arrived dry & didn’t appear to work. The second one appeared wet and it didn’t work. I should’ve have listened to all the poor reviews. I’m going to the spa store next time, It has also gotten very expensive compared to previous buy.
