Key Benefits at a Glance

• Helps reduce cloudiness caused by irregular alkalinity and supports clearer water
• Supports spa equipment by maintaining stable pH and protecting piping, heaters, and filters

How EcoOne pH Minus Works

When alkalinity is too high, pH tends to drift upward. This product dissolves in water and releases a mild acid that lowers pH over time as the water circulates. Regular testing ensures the water stays within a comfortable range.

Practical notes: the product is designed for use in pools, spas, and hot tubs, and it is compatible with EcoOne’s broader line of earth-friendly spa care items. The jar typically contains 2 pounds of powder, sufficient for multiple balancing sessions when used as directed.

Usage Guidelines

• Test the water pH. If above 7.8, prepare the solution by dissolving 2 ounces in a small amount of water.
• Pour the mixture directly into the spa or pool.
• Run the circulation system for several hours, then retest and repeat if necessary to reach 7.4–7.8.
