Pond Management with the use of Chemicals

Aquatic herbicides and algaecides (chemicals) have been useful tools for pond management for decades. Once a pond becomes infested with weeds and/or algae, a chemical application may be your best solution to gain control, at least for the short-term. It is important to understand that chemicals only fix the result of a problem and not the problem itself. The "problem" is an abundance of suspended nutrients and the organics (muck) that have settled to bottom of your pond. These factors can be contributed to a number of different things such as surface water runoff, grass clippings, and fertilizers, just to mention a few.
Some pond owners go as far as treating their pond once a week with chemicals to manage their weeds and algae problems. If you're in the group, that is a problem! Not only is it more expensive, it is adding to your problem. Every time weeds and algae are treated, they fall to the bottom only to breakdown and encourage future growth.
Use chemicals as a tool in your management practice, chemicals are an important part of any management plan as long as they are not the entire plan. Another important consideration when treating for weeds and algae is that sudden changes to water conditions can affect the ecosystem and aquatic life. Always remember to run your aeration system before and after chemical applications. This will increase oxygen levels and enhance the effectiveness of the application.
