Hello, dear readers. We continue to fill in the “Aquarium Habit” rubric and I have prepared for you another list of frequently asked questions that periodically come to me in the mail or are asked in the comments to various blog articles.
In various sources on aquarium in our slang, the phrase “biological balance in an aquarium” often sounds, but what it is, novice colleagues do not know. Biological equilibrium should be understood as the stability of the biological regime in an aquarium, as a result of which we observe clean and clear water, the plants grow quickly and have no various defects, the fish feel excellent, the fish do not get sick, the water does not cloud and there are no algae.
The key condition for achieving biological balance in an aquarium is to find a middle ground between the aquarium inhabitants and the plants. In addition, an important role is also played by the temperature and light conditions in the aquarium, proper and balanced feeding of fish and the care of the aquarium itself.
Question number 2 – In the aquarium, periodically there is a film on the surface. What to do and where does it come from?
To know how to deal with the appearance of the film, you need to know the cause of its origin and the type of the film itself. In the recently launched aquariums often appeared oily film, which stands out from poor-quality putty.
In modern and poorly closed aquariums, with excessive feeding of fish on the surface of the formed bacterial film of grayish-white color.
To remove the film from the surface of the water, it is enough to put a sheet of newspaper or other paper on the surface and, holding one edge, slowly lift it from the surface of the water. This operation is repeated until the film completely disappears.
It is clear that the piece of paper is not a panacea, you need to look for the reason for its appearance. Try first to reduce the dosage of fish food and turn on aeration in the aquarium, since aeration greatly prevents its appearance.
Question number 3 – On the ground formed a white moldy plaque. Where did he come from and how to deal with it?
The formation of white bloom at the bottom of the aquarium is a signal to the aquarist that the biological balance has been disturbed. The main reason for its formation is an excess of dry food when feeding fish. Also, this plaque can be formed as a result of excessive feeding with daphnia, cyclop, chopped bloodworm and a pipemaker.
It is necessary to feed fish so that it would be eaten within 10-15 minutes. Otherwise, everything that has not been eaten will settle to the bottom, will begin to decompose and will eventually be covered with mold. The presence of mold provokes the rapid development of harmful microorganisms.
To avoid this problem, you should regularly pick up the remnants of the uneaten food and fish excrement from the bottom using a special siphon.
The reasons for the appearance in the aquarium bacterial turbidity huge amount. But, as practice shows, there are two main reasons – poorly washed soil (which will have to be removed and washed again) and an excess of fish food.
Food begins to rot in the aquarium, there is an excess of organic matter, and colonies of bacteria develop, which eat this organic matter.
Often in newly launched aquariums, the water suddenly becomes cloudy a few days after launch, and after a while it clears and becomes clean as a tear. When you run an aquarium, do not rush to plant fish in it and plant plants in it.
The fish want to eat, and in the aquarium biological balance still does not smell. As a result of feeding the fish, we get the turbidity of the water as a result of a bacterial outbreak.
To avoid this, let the aquarium stand without living creatures for at least a week.
To neutralize the bacterial turbidity, you will have to siphon the soil, stop feeding the fish with dry food and give more animal food. In some sources, you can read that the authors advise the use of antibiotics to neutralize bacterial dregs. Do not do this better.
The best option is to fight in natural ways, for example, pour water into an aquarium from an already running aquarium, where the bio balance is in order.
Question number 5 – Why on the glasses of the aquarium quickly appears brown patina?
Brown deposits on the walls are brown algae. They appear in the aquarium for many reasons: poor insufficient lighting, the presence in the bank of poorly treated snags from the natural reservoir, an excess of organic compounds, etc.
If there is no filter in your tank, and you irregularly remove the excess of the uneaten food, it all settles on the walls, which ultimately causes the development of brown algae. A similar situation occurs in the case of digging ground or bottom fish species.
Question number 6 – Why is the water in the aquarium turned green and dimmed?
“Green water” is a symptom telling an aquarist that green algae is developing in his aqua. These algae appear in the event that there is an excess of lighting in the aquarium, both artificial and natural. To combat this scourge, you will have to empirically establish the optimal power of lighting devices.
If you suddenly put the aquarium near the window, it will have to cover the dense curtain.
Unfortunately, to achieve complete cleaning of the aquarium from green algae is extremely difficult and time consuming. For a start, you have to cover the aquarium with a dense cloth for 2-3 days, do not turn on the light in it, and also do not feed the fish all this time.
After feeding the fish, you will bring the next portion of organic matter to the aquarium, and your entire struggle will go down the drain.
