Why use pH UP?
Extreme pH levels must be avoided for the health of your pond. A pH range between 6.8 and 8.0 is ideal for garden ponds. Acid rain, mineral leaching, soil runoff, and decomposing plant and fish waste can causes unacceptable pH levels to occur.
pH UP works by slowly neutralizing acidic substances that cause low pH in pond water. It’s important to test the pH when using pH UP. pH should be raised no more than 0.5 units every 24 hours. Do not treat the pond more than once every 24 hours. Plants and algae cause a temporary increase in pH in the afternoon, therefore, pH should be tested in the morning to obtain the lowest reading. 473ML
