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.

Ran out of SpaUP, and needed to correct pH in our spa quickly. I paid a bit more for this than I would if I drove to the spa store, but knowingly paid extra for convenience. Works well, does it's job.
