Review: Great Product - Worked Great !

## Features

- 2 LB Hot Tub Alkalinity Increaser - Low alkalinity can lead to unstable pH and harder-to-manage spa water. This sodium bicarbonate formula helps raise total alkalinity to support balanced water chemistry and more stable pH levels in hot tubs and spas.
- Supports pH Stability - Balanced alkalinity helps buffer pH changes and lower frequent swings. For most spas, keeping alkalinity in the 80–140 ppm range supports stable water chemistry and easier maintenance.
- Helps Protect Spa Surfaces & Equipment - Balanced alkalinity helps prevent the pH swings that can lead to corrosion, etching, and scale formation, supporting the longevity of hot tub surfaces, heaters, and fittings.
- Fast-Dissolving Granules - The sodium bicarbonate granules dissolve quickly and spread evenly throughout circulating spa water. Test your levels, add 1 oz (2 tbsp) per dose, circulate for 30 minutes, and retest to confirm balance.
- Made In The USA - At AquaDoc, we make high-quality hot tub chemicals designed to support balanced, comfortable water. Proudly made in the USA with consistent quality standards.
