pH Min

An ideal pH value for a garden pond ranges between 7 and 8. At this level the water contains sufficient CO2 and there will be optimum growth of the water plants.Relatively high pH values (8.5 or higher) usually indicate that there is lack of CO2 in the pond water. Certainly if carbonate hardness (CH value) is low. Under these circumstances growth of oxygen producing plants will stagnate (waterweed, hornwort, etc.) and there will be excessive growth of algae (green water or fibrous algae). To decrease the pH value in the long run, you should take measures in biological sense. The issue at stake here is that you stimulate the development of the micro-organisms. Take care that 80% of the ground surface is covered with Pond substrate and mix it with a dose of Bacterial. Besides, it is wise to apply a number of floating plants. To reduce the pH value at short notice, pH Min of Velda can be used. The product will be acting in a very direct way and it is simply added to the water.
