## Overview

SpaGuard Rapid-Dissolve pH Decreaser Tabs are designed to quickly and effectively lower the pH levels of spa water, ensuring a comfortable soaking experience while protecting your spa equipment. Each 1.25 lb container provides convenient tablet dosing, with 2 tabs treating up to 250 gallons of water, making it an essential product for spa owners.

## 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

- Quickly decrease pH level of spa water. Provide soaker comfort and protect spa and swim spa equipment.
- 2 tabs per 250 gallons – 1000 liters as needed. Lowers pH 0.1 – 0.2 units.
- Convenient tabs that quickly respond to key challenges in smaller bodies of water like spas and swim spas.
