The water in the aquarium turned green: what does it say?

The poor condition of the water in the aquarium can have a negative impact on the health of the fish, the quality of the plants and the presentability of the internal design.

Opaque, muddy, with a specific odor and greenish-brown color water is a sign of putrefactive processes that take place inside, a signal that self-cleaning processes are not enough and that domestic artificial water bodies urgently need help, otherwise the water may completely drain.

The main reason is this: bacteria have got into the water, for reproduction of which in this aquarium there are necessary optimal conditions. What are the ways of infection:

  1. Poorly purified water;
  2. Sick fish;
  3. Infected feed;
  4. Affected algae;
  5. Contaminated soil.

Using settled tap water to fill the aquarium, aquarists understand that they deprive the inhabitants of the aquarium of some useful substances that are destroyed in the process of water preparation. However, water disinfection in centralized water supply networks is a guarantee of its bacterial safety. Non-disinfected water contains many bacteria, viruses and protozoa that show their pathogenic properties under favorable conditions, namely:

  1. low water mobility;
  2. lack of oxygen in it;
  3. temperature 24-27o;
  4. dim lighting.

The same mechanism of the development of putrefactive processes is observed when the infection with its inhabitants and algae is carried into the aquarium.

Factors contributing to the fact that water can rot, are:

  1. failure to follow basic sanitary and hygienic rules for maintaining an aquarium,
  2. poorly organized food (uneaten food settled to the bottom – a good start to the process of rotting),
  3. overpopulation of the unit volume of the home water body,
  4. the absence or inadequate power of hydraulic equipment (air pump, aerator, filter, lighting devices, etc.).

The first signs of trouble is the appearance of turbidity. It may have a yellowish white or greenish tint and be accompanied by a stale, stale smell. The observant owner of the aquarium will feel such processes even earlier, due to the appearance of a yellow bloom on the inner wall of the aquarium.

In addition, the consistency of water begins to acquire slightly slippery and soapy characteristics. Merging a part of the water and adding a new one is unlikely to help, because in this case the source of decay still remains inside and after some time the processes will develop again.

The second sign that the water in the aquarium has blossomed is the ill health of some fish species. Their behavior changes in the direction of depression, refusal of food, fading of color, refusal of reproduction and other symptoms.

Failure to take action can even lead to the death of individual individuals.

It can not affect the unhealthy green water and the state of the universal plants for the aquarium. They can shed their leaves, turn yellow, curl up into a tube, float to the surface, and contribute to more intensive reproduction of putrefactive bacteria.

Over time, bubbles may form on the surface of the water, and the water will become completely opaque and smelly.

If you feel that the water in the aquarium stinks, you should immediately begin to save the home pond.

In the aquarium, the water is rotten: what to do?

  1. Replant all living healthy creatures in another reservoir for a temporary stay and set them to watch. Patients should not be kept together with healthy ones to avoid re-infection;
  2. Water is drained to the highest possible level;
  3. Thoroughly wipe the walls;
  4. All artificial jewelry and soil boil or wash and process the disinfectants permitted for the antiseptic of drinking water;
  5. As much as possible to throw the affected plants, and rinse healthy bushes in running cold water, cleaning the root system as much as possible;
  6. Leave the components of the aquarium for some time in the open air to dry out, or even better in the bright sun.

Only after that you can fill the treated aquarium with water and inhabit the inhabitants.

In some cases, with very large volumes of aquariums, such procedures are complex and expensive. Then they resort to disinfecting water without draining it.

In this case, special attention should be paid to the quality and safety of the applied antiseptics and disinfectants, as well as compliance with instructions for their use.

The contents of any aquarium (from 20 liters round to 500 liters panoramic) is a complex balanced system formed by a biocenosis with its own properties. Any failure in its functioning can lead to the collapse of this complex and the death of the inhabitants of the aquarium.

Therefore, only constant dynamic observation and timely action can be a guarantee of well-being.
