Natural Pond Treatment
- A barley straw treatment is one of the easiest natural pond treatments to perform. Plus, it has the advantage of being inexpensive as well. You can buy barley straw at your local pond store or try online if you have trouble locating it. Barley straw works by releasing chemicals that prevent the formation of algae as they it decomposes. A rough estimate is that 4 oz. of barley straw will treat a pond of up to 800 gallons. For a larger pond, adjust the amount of barley in proportion. For example, in a 1600 gallon pond, you would use 8 oz. of barley. Some barley straw comes bunded in a mesh package, but if you are buying it loose, you can use the mesh bags that fruit comes packaged in at grocery stores. Weigh the sack down with some rocks and sink it to the bottom of your pond. Repeat every four months to keep your water algae-free.
- Water plants help absorb waste products produced by fish and other aquatic animals. These plants help maintain natural pond balance by adding oxygen to the water. They also provide shade for your fish. Consult your local pond supply shop for which species would work best with your pond size and fish choice.
- This is an important part of natural pond treatment that most water gardeners forget. The extra food left behind after a feed sinks to the bottom of the pond, where it decays and introduces unwanted chemicals into the pond ecosystem. This can also lead to algae growth. Follow an expert's guidelines on how often and what amount you feed your fish.
- Make sure to keep leaves and other debris out of the water. Purchase a net and skim the surface of the water every couple of days, more often in the fall. To get at the smaller muck, take a garden rake and tie a piece of cheesecloth to it. Then use this as a strainer to scoop up any detritus that has collected on the bottom of the pond.
- Fountains are a great way to naturally keep your pond healthy.
A water feature, such as a waterfall or fountain, will help oxygenate the water and keep it aerated. This is healthier for both fish and plants, as well as retarding the growth of algae.
- A biological filter works by filtering the water through a medium filled with beneficial bacteria. The medium can be nothing more than pieces of plastic or round balls. These filters also have some kind of straining element, such as a charcoal screen, that helps trap larger particles.
- There are a number of bacterial treatments that you can add to pond water. These are usually colonies of beneficial bacteria suspended in a solution that you add in diluted doses. They work by breaking down the harmful elements in the water that contribute to algae growth.
