1 The most important thing is to have an effective ecological filtration system, including mechanical filtration and biological filtration. The usual mechanical filtration can only remove solid pollutants, but there are still a lot of organic substances dissolved in water, such as protein, which cannot be filtered out, and can only be completed by biological filtration system.
The water in the fish tank is polluted by fish droppings, food residues and rotten leaves of aquatic plants. In people's imagination, filtering out the visible suspended solids in the water and keeping the water clear and transparent will achieve the goal. In fact, this is only the primary function of filtration, which we usually call mechanical filtration. Modern ornamental fish tank filtration should have both mechanical filtration and biological filtration, and sometimes physical filtration is needed. Among them, biological filtration is particularly important. The so-called biological filtration is to decompose or convert harmful substances dissolved in water into harmless substances through bacteria attached to filter materials. Physical filtration uses the unique adsorption function of some materials to purify water. Physical filtration is only used for a short time under special circumstances, such as removing residual chemicals in water.
The filtering capacity of the filter should be large enough. The filtration capacity of the filter is expressed in liters/hour. When filtering water, it is generally required that the filtration volume reaches 4-7 filtration cycles. Specifically, if the water in the fish tank is 200 liters, a filter of 800- 1500 liters/hour should be equipped.
The amount of fish and bait should be moderate. If the honey juice of fish is too big and the bait is too much, it will aggravate the pollution.
Aquatic plants are also a good helper to purify water quality, so we should raise as many aquatic plants as possible and turn the whole aquarium into a small ecological paradise.
By putting scavengers and mossy shrimps in the tank, we can remove the dirt and algae attached to the tank wall.
With the above conditions, the water in your aquarium will naturally be clean.
The water in your fish tank turns green quickly, which has nothing to do with raising aquatic plants. It is caused by the rapid reproduction of aquatic plants. Don't put your fish tank where it can shine in the sun. In addition to being prominent and conspicuous, the ideal place to put the fish tank should be a quiet place away from the window. Quiet is very important for some high-blocking fish. They are easily frightened by noise and movement. Some frightened fish will get sick or even die. The light outside the window will cause algae to grow wildly and fish to tilt. Therefore, the fish tank should be placed in a dark place without direct sunlight, which will not only disturb the fish less, but also have a good ornamental effect and inhibit the growth of algae. To completely solve the harm of algae, we must rely on the cooperation of the above five measures.
Hope to adopt. Thank you.
