A large number of pond owners are misconceived when it comes to the presence of algae in aquatic structures. The problem occurs where the algae is growing prolifically often distorting the color and the texture of the water. A poor quality of water can actually stress and stunt the growth of fish and therefore understanding ways of keeping your pond clean and fresh can create a balanced ecosystem.
Where the water quality is not maintained, ammonia levels will be on the rise impacting on the health of fish. In a large number of cases, it will result in poor gill function and an inability for the Koi to breathe. Apart from the devastating impact on fish, the presence of large amounts of algae can create an unattractive looking feature.
It is important to implement methods that will keep the correct balance of both algae and bacteria so that a healthy ecosystem is maintained. Where matter and waste are allowed to collect in the bottom of the pond, the oxygen content eventually decreases, which means that beneficial bacteria or microorganisms are unable to control for high levels of ammonia and nitrites. Even the application of a pump or filter to aerate the water will prove ineffective.
Increased exposure to sunlight during the warmer months creates the ideal conditions for algae growth. The key is to manage the amount of waste entering water in order to control ammonia and nitrite levels. The implementation of aquatic bacteria to break down the high organic content safely and naturally can prove most successful.
Be sure to avoid placing large number of aquatic plants, twigs, branches and similar objects in the water as this will breakdown over time increasing the nutrient rich content in the pond. With effective microorganisms and aeration systems in place the bacteria will begin to eat the extra nutrients and muck settling in the bottom of ponds for clearer water. Where you are able to reposition plants to provide shade and clean out filters, it may give the beneficial bacteria an opportunity to repopulate.
There are many products available to add the necessary microorganisms to the pond. Once these have been added it will work to decrease ammonia and nitrates and increase the overall oxygen content. The result is a drastic reduction in the presence of algae as all organic content is broken down without any harm to the fish present in the water.
Should the water turn a brown color, clear the area of all debris and leaf matter that may have fallen into the pond and settled on the bottom. The addition of suitable microorganisms will allow for acceleration in the break down of any remaining leaf or organic matter. Over time you will also notice the water beginning to clear and reduce the collection of sediment.
To keep your pond looking clean, fresh and have the algae under control with effective microorganisms it is important to exercise regular maintenance. This includes cleaning filters, checking aeration systems and introducing beneficial bacteria. This will enhance the desired microorganism populations and the breakdown of excess waste.
