Description
pH Adjuster For Ponds. Slowly raises the pH of pond water (making it more alkaline) without harming delicate pond fish or aquatic plants. Slowly neutralizes acid substances that cause low pH (pH of pond water is affected by mineral leaching, soil runoff & decomposing waste). A low pH can stress pond fish & suppress the activity of the biological filter. **16-ounce **Contains no algae-promoting phosphates **Amount treated depends on the degree of change in pH needed
