This product is a special compound used to increase the total alkalinity in spa water. Test for total alkalinity with a reliable test kit. The desired range for total alkalinity is 80-140 ppm. This product increases the effectiveness of the disinfectant, and helps prevent scale formation. It also prevents corrosion of metals, etching of spa surfaces, eliminates “bounce”, and maintains pH at the proper level. Easy to use; dissolves quickly. 1. Add 1 oz. (2 tbsp.) to spa water. 2. Allow water to circulate for 30 minutes. 3. Retest water and repeat Steps 1 and 2 until the desired level is reached. For best results, dissolve granular products first by adding to a small plastic pail filled with water.

The hardest chemical balance I get with my well water is the alkalinity. This product is great for me because it increases the alkalinity to keep my hot tub water within the normal ranges. The size and quantity of the bottle is limited but with the price. Sometimes I have to add a lot of the bottle instead of just a lid full. It’s easy to open for an adult who knows how to squeeze the lid and twist. Overall the functionality of it works as it says it should.

These are good tablets. They worked, but they did seem to disintegrate quicker than other ones I have bought.

This works great for my hot tub. My hot tub was getting a little slimy and dirty and I put like a cap full of the sun and ran it for about 20 minutes and it came beautifully clear and clean. I will definitely be purchasing the stuff again.
