API – Pond pH up
API – Pond pH up adjuster slowly raises the pH of pond water, making it more alkaline, without harming delicate fish or aquatic plants. It slowly neutralizes acid substances that contribute to low pH, which can stress pond fish and suppress the activity of your pond’s natural biological filter.
Test the pH level of the water with an API Test Kit. Use the dosing cap on the bottle. Add 10 ml. for each 50 gallons of pond water. For best results, add to water flow. Wait 24 hours, then test pH again. Repeat treatment as necessary.
