How to get rid of the smell in the aquarium :: should the aquarium smell like :: Apartment and cottage :: Other

Some novice aquarists are faced with this situation: recently changed water suddenly begins to emit a whole bunch of unpleasant odors. The solution to this problem depends on the cause of the stench, and there may be several ways out.

The question “how to restore the certificate of registration of ownership of 1/4 apartments, the type of registered right is a common shared ownership” – 1 answer

1. The first thing that can be done is to thoroughly clean the aquarium and everything that is in it (stones, shells, decorative castles, houses, etc.). Rinse the inside of the glass well, as even if at first glance they seem to be clean, they may still have a slippery water stain on them.

If a few days later from the aquarium again smells unpleasant, you need to look for more reasons in more detail.

2. First, determine which smell comes from your tank. If it smells a bit of mud or swamp, you can calm down.

This fragrance means only that everything is in order with him and his inhabitants. This aquarium should smell like a river.

3. If you feel completely different unpleasant odors – rotten eggs, onions or garlic, you must take decisive action. The smell of onions can produce some aquatic plants. For example, if in your aquarium cryptocarins live, there may be such a smell.

In this case, add to them a pair of ambulium bushes, a little hornpole, and a few hemianthus bushes. Unpleasant aroma should disappear.

4. The cause of the unpleasant the smell there may be impurities that accumulate at the bottom of the “pond” – these are both waste products of fish, and remnants of food. If the aquarium is too large and there is no possibility to wash it completely, just draw a primer siphon.

For this purpose, a special device is used in the form of a hose with a tip through which water passes, taking with it all the accumulated dirt.

5. Together with the ground siphon it is necessary to carry out the process of partial replacement of water. This will also help to heal the atmosphere and remove substances harmful to fish.

This should be done twice a week, at the same time it is necessary to replace from 20 to 30% of the water in the aquarium. You can use ordinary tap water, but it must be defended during the day.

6. Determine if the fish have enough oxygen. To do this, see if they float close to the surface, gasping for air.

In this case, you need to buy a good air compressor, which must constantly work, providing good aeration.

Beautiful and harmoniously located in the room aquarium can be a decoration for any interior. Aquarium – a great way to relax and achieve internal balance. However, the fish themselves and their house need constant and competent care.

Beginners and even experienced aquarists often encounter undesirable and unpleasant situations that are the result of improper or inadequate care. One of these situations is when the water in the aquarium smells unpleasant.

Let’s try to find out why aquarium water smells, and what actions you can take to eliminate unwanted odors from the aquarium.

With a situation where water smells unpleasant or even stinks, I come across, perhaps, every fan of aquarium fish. The causes of this phenomenon may be different:

  • Aquarium has not been cleaned for a long time. If you do not know, the dwelling for fish and other underwater inhabitants should be periodically cleaned, washing both the soil and algae and the glass of the aquarium. It should also regularly change the water. The smaller the aquarium, the more frequent cleaning it needs.
  • Poor quality fish food. Overdue feed can easily lead to rotting bacteria in the aquatic environment and in the soil. If you find an unpleasant odor in a relatively clean aquarium, try changing the type of food – if the problem disappears, then it’s a matter of poor nutrition.
  • Excess feed. Food is quite normal, but it is possible that you give it in excess. Feed particles that are not eaten gradually settle to the bottom and turn into the ideal substrate for the reproduction of microorganisms.
  • Overpopulation of aquarium. Such a problem is often encountered by novice aquarists who try to fit as many fish of various sizes and species as possible into a standard tank. It should be remembered that the aquarium is a kind of closed biosystem, which must be in harmony and balance. If the house has more residents than it should be, inevitably problems arise with the cleanliness of the premises.
  • The presence of some specific plants. Some types of algae can produce a peculiar smell. It is better to immediately clarify this point during the purchase of plants in the store. Again, the smaller the capacity, the more noticeable the vital activity of plant organisms: in a large volume of water the odor from algae is leveled.
  • Ground souring: methane release by soil bacteria.
  • Lack of oxygen. Deficiency o2 need to be removed with the help of a special device with the function of air circulation or a conventional compressor. Constantly high oxygen content in the water does not allow bacteria of the anaerobic type to multiply rapidly.
  • Too bright light. The abundance of radiation can lead to the multiplication and growth of unicellular algae, which, in turn, can produce unpleasant odors.
  • Too dim light. The lack of radiation causes the active growth of other algae, which also adversely affects the state of the water.

So, in most cases, the unpleasant smell of water is a consequence of excessive activity of putrefactive bacteria or plant organisms. Therefore, the main task of an aquarist is not to allow microorganisms to multiply too intensively, and for plants to bloom too much.

Suppose you figure out why the water smells in an aquarium. What measures should be taken to eliminate this problem?

The first thing you can do is to carefully clean the aquarium with all its contents. General cleaning is carried out according to certain rules. It is necessary to consistently clean the walls, bottom, stones, algae and all other elements of the home for fish.

Rotted algae and excess plants should be removed.

Replacing the water in the aquarium is carried out gradually – it can take 5-7 days. A complete and simultaneous change of water is carried out in exceptional cases: it is a huge stress for fish, which can lead to the death of fry and especially sensitive species.

Other methods of combating an unpleasant odor are saturation of water with a sufficient amount of oxygen, changing the feed or regulating its amount, ensuring the optimum amount of light emission. If the aquarium is overpopulated, a part of the inhabitants should be transplanted into another container, sold or donated: it is better to lose some of the pets than to constantly face the problem of abundance of feces and harmful bacteria.

In an overpopulated aquarium, fish feel uneasy and often show aggression towards each other.
