Maintaining the proper pH value in your pond is very important for your fish and plants. Most pond plants thrive at pH values of 6.6 to 7.2. Small variations of up to 0.2 are acceptable and do not require adjustment. Stable values are important. Ponds that contain cement, mortar, or rocks (all of which can raise pH) often require pH adjustment. Laguna pH Adjust Down safely lowers pH levels that are too high. The treatment is beneficial for both pond fish and plants.
