There are numerous pond chemicals available to keep your pond chemically safe. Each pond chemical is responsible for a different aspect of your pond's health. This can be confusing for beginner water gardeners. The first set of chemicals is designed to keep your pond water clear. Another set of pond chemicals are introduced to urge the absorption of sunlight to urge the growth of aquatic weeds and submerged algae. Others darken the water to lessen sunlight for fish and algae growth. There are also chemicals that eliminate ammonia and keep pH levels balanced. Before purchasing chemicals for your pond it's wise to seek the advice of a pond specialist. For example, ponds with aquatic plants will require a separate set of chemicals then fish ponds. Remember that pond chemicals are applied on a schedule specific to your pond's demands, so always read and follow the instructions carefully before administering pond chemicals.
