How to Eliminate Pond Algae
Pond alga is one of the most common issues people deal with when maintaining their man made pond. One of the biggest problems is that this alga can grow quite rapidly and spread throughout the pond reducing visibility in the pond. Since algae can spread extremely fast, it is important to treat your pond at the very early stages of its growth.
Types of Pond Algae
There are two main types of pond algae, including blanket algae and green algae. Blanket algae develops as long strands that will bind together as they get longer. When this happen, it will look like a blanket of algae covering your pond. Green algae, on the other hand, will discolor the water in the pond and give it a greenish color. This green algae can become so thick that you will not be able to see the fish in the water.
Both types of algae require oxygen to live. During the daytime hours, the sun’s rays allow these simple plants to produce their own oxygen. However, after the sun goes down, the plant will pull oxygen from the water in the pond. This, in turn, leaves less oxygen in the water, which the fish need to survive. If left untreated, this lack of oxygen can kill the fish and other plants in the pond.
Proper Plant-Fish Balance
One of the main reasons pond algae is so prevalent in manmade ponds it that there is an improper plant-fish balance. All types of fish, including Koi and goldfish, emit nutrients into the water. When there are plenty of plants in the pond, these nutrients are adequately absorbed by the plants. However, when there are not enough plants, this increase in nutrients in the water creates the perfect environment for algae growth.
Both floating and submerged plants are great options for any manmade pond. The floating plants can block the sunlight making it difficult for algae to produce the oxygen it needs to survive. The submerged plants will add oxygen directly into the water for the fish to use.
Effective Ways to Get Rid of Pond Algae
There are many products on the market that can be used to fight algae effectively. Many times, several rounds of treatment are necessary to treat the algae outbreak completely. The most important thing is to consistently check the water conditions and immediately use treatment at the first signs of algae.
UV clarifiers are also very effective. It works by killing the algae, by use ultra violet rays. If you are experiencing blanket algae, you will first need to get rid of the current algae on the pond, by pulling it out by hand or by using a high-powered hose. Once the algae is all gone, you can treat to prevent future algae growth.
Pond algae can be eliminated from your pond with just a few simple treatments. However, the sooner you start treatment, the quicker results you will see. This is why it is so important to check your pond on a regular basis. You may also want to add more plants to the pond area to prevent a future problem of pond algae.
