Easy to use and highly effective, they protect spa equipment from corrosion and ensure optimal bather comfort by maintaining the ideal pH range of 7.2-7.6. Trusted by spa owners for reliable, hassle-free water balance management. ## Description These tabs are compressed versions of the traditional pH Decreaser, sodium bisulfate. They are smaller than the standard 1”, but 1 tab per 250 gallons will lower the pH by 0.1-0.2 units. These tabs dissolve via erosion. While these tabs don’t effervesce when placed in the spa filter compartment with jets operating, they will dissolve in just a few minutes. Since the average pH of a spa tends to rise daily, a pH decreasing product is a must-have. Applying directly to the footwell promote a slower dissolution experience and is not recommended. It is important to not leave any undissolved material in the footwells or surfaces of the spa. If applying directly to the water, brush away any undissolved material. Due to their ease of use, customers who often adjust pH could dose more frequently. As with making pH adjustments using a granular pH decreaser, the total alkalinity will drop along with the pH. As a result, the total alkalinity might require more frequent adjustments. ## Features - pH Decreaser: SpaGuard Rapid-Dissolve pH Decreaser Tabs will quickly lower the pH level of water in spas. The pH level should be maintained at 7.2-7.6 as measured by an accurate test strip or kit. - Safe & Easy To Use: This dry tablet is easier to use than liquid acids. Using this product regularly will help make maintaining proper water balance a breeze. - Easy Application: Simply drop a tab in the filter well, then watch it disperse chemicals without any added effort achieving maximum bather comfort. - Protect Spa Equipment & Surfaces: Rapid-Dissolve pH Decreaser Tabs help maintain the proper pH balance, preventing fluctuations that can lead to equipment corrosion and discomfort for bathers. - Tested and Proven Effective: SpaGuard products are known for delivering reliable results and making spa care less complex.
