Cloudy Aquarium – Why And How To Solve It

The aquarium is a great addition to the interior. The aesthetics of wildlife creates a special atmosphere that favorably affects the mental health of the residents of the house. But the appearance of the aquarium is not always kept in perfect condition: very often the water in aquarium becomes cloudy or green, and an unpleasant odor appears. It is not difficult to overcome this phenomenon, the main thing is to find out the cause of its occurrence.

Causes of Cloudy Aquarium

The aquatic ecosystem inside the aquarium can be disturbed for both objective (independent of humans) and subjective (when the owner is to blame) reasons. The liquid in the aquarium is the habitat of not only the fish placed there, but also a huge number of microorganisms, as well as algae, which can make their own adjustments to the color and smell. Housing aquatic pets requires quality care, as well as a cleaning system and adequate lighting. Experts identify several main reasons for cloudy aquarium.

1. Raising the ground

This reason is relevant if veil-tails, goldfish, catfish, cichlids and other fish that love to dig in the process of finding food are chosen as pets. This problem resolves by itself within a few hours, but has a tendency to relapse.

2. Accumulation of metabolic products and development of microorganisms

This problem arises in cases where the artificial fish house is not equipped with a filtration and blowing system, and there is either no or very little vegetation. In this case, the aquatic ecosystem becomes extremely favorable for the reproduction and prosperity of bacteria, which not only lead to cloudy water, but are also harmful to fish and plants.

The reasons for the development of harmful microorganisms also include an excessive number of fish per 1 cubic meter of water and / or excessive feeding. It is important to adhere to the rule here: it is better to underfeed an aquatic animal than overfeed. To solve the problem, you need to clean the glass container and replace the liquid. To do this, you need to transplant the living creatures into another tank with water.

3. Fresh water (first week)

This factor is one of the most common, but it has an easy solution. The essence of the problem is a huge number of bacteria, the solution is to wait a few days without introducing fish into the aquarium. Thus, the lack of food will lead to the disappearance of microorganisms, and the water biological balance will return to normal.

4. Reproduction of algae

If the water turns green, this means that the aquarium flora is in an active breeding phase. Excessive lighting can contribute to this. This issue can be solved by briefly reducing the duration and frequency of artificial lighting, as well as excluding the possibility of direct sunlight.

An excess of nitrates or phosphates is another reason that provokes the growth and reproduction of plants. These substances come along with the food that is fed to the fish, or with tap water. If the reason lies in food, then it is worth underfeeding your pets a little or changing food. If water is the culprit, then it’s worth replacing it.

5. Chemicals

Very often, owners want to quickly clean the aquarium, especially if it stinks, using various auxiliary detergents. But at the same time, some of them change the pH of the water, thereby creating a danger to the health of the fish. In this case, it is reasonable to transfer the pets to another, clean tank, thoroughly rinsing the aquarium.

6. Poorly washed gravel

A gray and whitish color of the aquarium liquid indicates that it is necessary to rinse the aquarium more thoroughly. It must be cleaned so that the water after rinsing is crystal clear. A similar shade can also be produced by heavy metal or phosphate, in which case it is necessary to change the decoration.

7. Wooden accessories and peat filters

These aquarium décor elements can give a brown tint. This is due to the release of humic acids and tannin, which are not always safe for the health of fish and can lead to their poisoning. Before using wooden structures, it is worth soaking them first. To solve an existing problem, you can change the water several times or throw a couple of tablets of activated carbon into it, which absorbs substances that change color.

8. Medicines

Has the aquarium lost its aesthetics due to the need to cure the pets? What to do? Everything is very simple: it is worth using activated charcoal, while the water will be clear, and everything will be fine with the fish, because their treatment will continue.

9. Dirt that the filter cannot deal with (or if it is missing)

In this case, it is worth getting a lid for the aquarium and changing the water.

Dealing with muddy or milky water and unpleasant odors in an aquarium is a laborious process, and if you also take into account the fact that you first need to accurately determine the cause of the problem, this mission becomes even more difficult. That is why it is better to prevent the problem than to solve it. 

Several ways to deal with a cloudy aquarium :

  • acquire a powerful and reliable purification system (with a filter, the water will remain transparent for as long as possible and have a pleasant smell).
  • before installing decorations in the aquarium, you should consult with a specialist (he will recommend what is better to choose and how to care for the decorations).
  • get acquainted with the possible causes of water spoilage (if possible, avoid them).
  • use the aquarium cover (especially when cleaning the house).
  • do not change the water all at once (an exception may be an emergency) – this is necessary to maintain the water balance.
  • do not overpopulate the “fish house”.
  • clean soil, stones and other decorations (if any).

Sadly, but fish have a fairly short life. That is why it is worth watching over their condition, because if you skip and do not remove the dead fish from the aquarium, the water in it will deteriorate, acquire a very unpleasant aroma that will be difficult to remove.

In addition, it is also worth noting the procedure for selecting and replacing water. Here it is important to determine the presence of impurities, acidity and temperature. If impurities can change color and odor, improper temperature and acidity can even kill the fish. Therefore, it is worth acquiring special equipment in advance.

Experts do not recommend using a chemical method for cleaning aquarium liquid. Why is that? The use of cleaning and odor-removing products can negatively affect the health of aquatic pets, which often leads to their death.
