Optimal pH Adjustment: The ideal pH value for most plants is 5.5 to 6.5. Using a pH-balancing solution allows you to precisely adjust the pH of the nutrient solution to suit the needs of different plants. A balanced pH value improves nutrient utilization, promotes vigorous root growth, enhances water uptake, and improves crop yield and quality.
Freshwater Aquarium Water pH Adjuster: When the pH is too high, it can affect the fish's respiratory function. Use the pH down regulator to raise the pH of the Aquarium Water to a suitable level for fish. When adjusting the pH, do so slowly to avoid sudden changes in the pH value that could stress the fish. Shake well before use and add 20ml of pH down liquid to every 100 liters of water. Then measure the pH and adjust the dosage accordingly. Generally, the daily change in the pH value should not exceed 0.5.
