Why is koi pond green

Here is what has happened. How do you control algae blooms? The way it works is simple. Once the algae dies, the dead cells start to decompose and begin sticking to one another. Once you install an ultraviolet light, this process can take about a week before the water becomes clear again.

In the second situation, your pond water may be clear. However, stringy green algae reaching 1 to 2 feet in length are rapidly beginning to grow on the waterfall or throughout the pond. You have to add the right quantity. Those of you who are overstocked with the amount of you keep are destined for disaster!

More fish in the pond means more natural biological processes. Fish then produce more faecal waste that forms the nutrients required for green water to occur. Research the amount of fish suitable for the volume of water in your pond. By keeping a decent amount of fish for the size of the pond, you prevent an overload of waste and reduce the nutrients available to trigger the growth of green water algae. Similar to overstocking fish. Leftover fish food decomposes in the pond and turns into waste that also fuels the growth of green water.

This is most likely to occur in your pond during winter months when fish have a reduced appetite. Green water causing algae are plants, and like any other plant, they love sunshine.

Aquatic plants such as water lilies which float on the surface are a great method. They provide partial shade to reduce sunlight exposure not only to algae but for fish such as Koi, which can be sensitive to sunburn.

As mentioned before, green water is caused by single-celled plant organisms called algae. This organism typically occurs when there is an imbalance high amount of nitrates and phosphate levels in pond water providing algae with the nutrients to grow and in perfect conditions, thrive! These nutrients are elevated via some of the points mentioned above, however, can be eliminated with the use of a beneficial bacteria treatment, such as Pond Klear. Pond Klear, therefore, prevents green water algae from growing.

Aeration devices are a useful way to increase the amount of oxygen in your pond that helps beneficial bacteria to break down and eliminate green water algae. As this sludge decomposes it releases lots of nutrients into the water, these nutrients provide food for the algae to grow, as more and more sludge builds up more nutrients are released which feeds the algae, before long the pond turns green with algae.

You also have to think of reproduction, goldfish may not grow as big as something like a Koi fish. Yes they do and maybe not as you think, a lack of plants rather than too many plants effect your ponds water. Pond plants consume nitrates and phosphate which is the same foods that the algae that are responsible for turning a pond green love to eat, so the more plants in your pond the more food is going to be consumed by the plants which leaves less food for the algae.

Floating pond plants such as water lilies and water lettuce will reduce the amount of sunlight that hits the water, this can help reduce the algae in a pond as algae need sunlight to thrive. There are three ways to get rid of the green algae in your garden pond but which is best for you and your fish.

A UVC is a unit that has a chamber holding an electric tubular florescent lamp that emits UV light, they are housed in a dark housing to protect humans eyes from coming into contact with the harmful UV light. They work by allowing the green pond water to enter the clarifiers inlet tube and travel past the UV light which is usually encased in a quartz sleeve to stop water from getting into the electrics.

Apply a sufficient amount of bottom substrate. It is a good place for bacteria to adhere, thus securing activation of micro-organisms. Apply more pond plants which do not have to rely on the water for their CO2 provision.
