<\/div>\n

Many fish friends will find that after a period of time to raise fish, fish pond water becomes green, wash the pool, change the water tossed some less than a month and become green, this is why?<\/span><\/span><\/p>\n

Fish pond water turns green is one of the problems we often encounter, often sudden outbreaks affecting the ornamental, today we will nag green water causes and solutions.<\/span><\/span><\/p>\n

First.<\/span><\/span>chlorella<\/span><\/span><\/strong>(commonly known as green algae), are organisms that have thrived on Earth since 540 million years ago. Chlorella is the main culprit when the water in a fish pond turns green. Fish ponds are open to the air and the algae inside reproduce faster under photosynthesis, so fish ponds that see direct light tend to turn green. Some people say you can use algae remover to solve the problem, but have you noticed that after a few days the algae still grows rapidly and can't solve the fundamental problem, so this method can only be used in emergency, it is not desirable.<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

Chlorella is a highly efficient photosynthetic plant that reproduces by photosynthetic autotrophic growth. Many fish enthusiasts are struggling in the hope of removing chlorella from their fish ponds, and for ornamental fish, the presence of chlorella is a real eyesore.<\/span><\/p>\n

Chlorella stabilizes and purifies the water, absorbs and transforms toxic substances, which is beneficial for fish ponds, but because many fish enthusiasts find it an eyesore, they are actively removing the green water.<\/span><\/p>\n

<\/span><\/p>\n

<\/p>\n

<\/span><\/p>\n

Chlorella grows most rapidly in water that contains more organic matter and can form dominant species because organic matter is broken down by bacteria into ammonia and eventually nitrates, which are the food source for chlorella. They will continue to divide when food is plentiful and there is enough light, causing the water to suddenly turn green within a day. The main thing that limits the growth of Chlorella is the ratio between nitrogen and phosphorus, when their ratio reaches<\/span>7.1<\/span>(particle used for comparison and \"-er than\")<\/span>3.0<\/span>Chlorella grows the fastest when it's in the water, and generally we don't have high levels of phosphorus in our fish ponds, so even if the nitrogen is higher the water is more fertilized green water doesn't happen.<\/span><\/span><\/p>\n

If the growth of Chlorella is restricted, the number of algal cells is usually maintained stably<\/span>2-3<\/span>If there is still no favorable environment for the growth of chlorella after a week, they will die in large numbers and the number of cells will decrease rapidly. We fish friends often use various methods to remove, but please do not be anxious, is the correct method of chlorella will still exist for half a month. This is one of the reasons why people feel that the greenish water in the fish pond is very stubborn.<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

In fact, green algae and moss can purify and stabilize the water quality, absorbing and transforming harmful substances, it is a kind of beneficial organisms to the fish pond, and we do not recommend to use pharmaceuticals to completely remove it. However, the water is too green to affect the ornamental properties, which is undoubtedly, simply can not see the koi, so many fish friends to ask me: how to control the growth of green algae, the fish pond can be clear to the bottom of my koi keeping the original heart?<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

Now that you've found the root cause of your fish pond water turning green, the next step is the solution:<\/span><\/span><\/strong><\/p>\n

1, Establish a sound filtration system: eliminate ammonia, nitrogen, and nitrates. This includes enhanced physical filtration to filter out as much food and fecal debris as possible, reducing the opportunity for organic matter to be broken down by bacteria into ammonia and phosphates.<\/span><\/span><\/p>\n

A, There are two ways to set up a filtration system, building a filtration pond and installing an integrated fish pond filter. The construction of the filtration pool and the precautions are shared in the previous article, you can flip through it if you are interested, welcome to leave a message in the comment section, thanks for your attention.<\/span><\/span><\/p>\n

B, If your pool did not plan a filter pool at the beginning of the construction, then the integrated fish pool filter is the best choice. Intelligent integrated fish pond filter, set physical filtration, biochemical filtration, sterilization, algae removal, oxygenation cycle as one of the water treatment equipment. Through the principle of physical and biochemical filtration, the particles of impurities visible to the naked eye in the water are filtered in the physical filtration bin, and then the water passes through the living filtration bin is to decompose the ammonia, nitrogen, nitrate and other substances. The specially designed built-in sterilization lamp can destroy the biological<\/span>DNA<\/span>It can sterilize and destroy algae at the same time, and generally<\/span>3<\/span>Results can be seen in about days.<\/span>7<\/span>Days you can see the water quality clear to the bottom. At the same time will also add oxygen to the fish pond, with scientific and effective fish pond filtration system, to realize fully automatic fish pond water circulation filtration, water purification, half a year or a year or so to clean the filter material, but also you have a clear water fish beautiful fish pond!<\/span><\/span><\/p>\n


<\/span><\/span><\/p>\n

<\/span><\/span><\/p>\n

<\/p>\n

<\/span><\/span><\/p>\n

2, reduce or minimize sources of organic matter. This includes reducing the stocking density of fish and reducing feeding when temperatures are high or very low.<\/span><\/span><\/p>\n

3, light should be appropriate. Chlorella undergoes intense photosynthesis in strong light and grows rapidly. Coupled with too much lighting, green water will surely erupt. Especially in direct sunlight.<\/span><\/span><\/p>\n

\u25b6stopgap solution<\/span><\/span><\/strong><\/p>\n

1, with a germicidal lamp:<\/span><\/span><\/strong>UVGermicidal lamps can destroy organisms<\/span>DNA<\/span>, which can sterilize as well as destroy algae, can be used to eliminate single-celled chlorella from the water. Generally about<\/span>3<\/span>The green water will be gone in about a day or so, and at the slowest it will be no more than<\/span>10<\/span>Days.<\/span><\/span><\/p>\n

2Coagulants<\/span><\/span><\/strong>: Filter out the planktonic algae condensation, not recommended, too much is harmful to fish.<\/span><\/span><\/p>\n

3, biological control:<\/span><\/span><\/strong>Use daphnia to eat the chlorella away, provided there are no daphnia-eating fish in the pool.<\/span><\/span><\/p>\n

4, salinity control:<\/span><\/span><\/strong>Chlorella is a narrow saline organism and is sensitive to increases in salinity, so adding salt to the water is helpful in green water elimination.<\/span><\/span><\/p>\n

5, with an algaecide:<\/span><\/span><\/strong>Although it can get rid of algae, it is not recommended because it is an agent that is harmful to fish and grass.<\/span><\/span><\/p>\n

6, inhibiting growth:<\/span><\/span><\/strong>It can be safer to reduce light, feed less, and step up water changes, the downside is that it will take longer.<\/span><\/span><\/p>\n
