API Pond pH Up Solution 16 fl. oz
API Pond pH Up Solution is designed to safely and quickly raise the pH in your freshwater pond to achieve more alkaline water conditions. pH measures the acidity or alkalinity of water. A pH level of 7.0 is neutral, levels above 7.0 are alkaline, and levels below 7.0 are acidic. Different fish species require specific pH ranges to thrive. Extreme pH levels can cause stress, illness, or death, making regular pH testing essential for fish health. This solution is colorless and does not cloud or alter the water color. It is phosphate- and nitrate-free, so it won’t promote algae growth.
