Fish farming, water culture, water culture, bacteria.
In order to raise nitrifying bacteria, many aquarists are trying their best. Today we will start from the most basic filter media, the filter material is the breeding place of nitrifying bacteria, nitrifying bacteria have a good place to live, in order to be more healthy, in order to work hard for the fish tank water body, today with the deer million to see what kind of filter material is suitable for your home fish.
Various filter media
Filter media usage scenarios
Used in filters, filter barrels, bottom filtration, drip boxes
Various filter media
The role of the filter media
The filter media is a hotbed of nitrifying bacteria, which can filter out heavy metals such as ammonia, nitrogen nitrite, and hydrogen sulfide in the water. The holes are more hydrophilic and can be well adsorbed by fish feces, water residues, etc., which are used as food to cultivate nitrifying bacteria. Purify the water quality, remove odors in the water, and maintain a healthy fish body.
1. Volcanic stone
After a volcanic eruption, the magma cools rapidly, and the gases inside quickly overflow and expand to form a densely porous glass lava.
Advantages: many holes and natural, less pollution, can increase the content of oxygen ions in the water. The pH value is stable, unlike some filter media that will make the water quality too acidic after a long time. For fish species such as luohan fish and parrot fish that need bright colors, the color of volcanic rocks is bright, which can also play a role in increasing the color of fish. In addition, for grass tank aquaclists, volcanic rock is also very suitable for aquatic grass climbing to stabilize the rhizome, and is also suitable as a culture medium.
The disadvantage is that the shape is irregular, and a certain amount of filter space will be wasted when placed.
2. Coral bone coral sand
Corals in the sea are deposited in the sea after death, the main component is CACO3, which is mostly like a branch. The remains of corals in the sea are also an important habitat for many marine life. Because of its abundant micropores and suitable for the survival of a large number of nitrifying bacteria, many sea tank players prefer to use it as a filter media. In addition, it can also be used for landscaping.
It should be noted that coral sand ph is higher than 7, alkaline, like peacock fish, blue pearl are suitable for weak alkaline, alkaline water. Coral stone will make the water quality harden, change the water quality, always pay attention to the change of water quality and replace the filter media.
3. Ceramic ring
Kaolin is artificially fired and is a relatively primitive filter material. The ceramic ring has many micropores, which can provide a lot of living space for microorganisms and nitrifying bacteria. Corrosion resistance, does not affect the water quality, will not affect the pH value of the water, the focus is on cost-effective, many people will choose it.
4. Germ house
Also known as a glass ring, artificially fired by talcum powder, there are more holes, the surface area is larger than the ceramic ring, which can provide a larger living area of nitrifying bacteria, which is very suitable for large fish tanks. It is also used by more aquarists at home now. The most common thing in the bacterium house is this yellow strip shape, which is neatly stacked to cure obsessive-compulsive disorder patients
Nowadays, there are other bacteria houses of different shapes, and the industry is also continuously rolled up, whether it is 3D, 4D or nano-level,
All in order to provide more holes, smaller volumes and higher water filtration efficiency. There are some mixes in price.
5. Quartz ball
This quartz pellet is small in size and suitable for small drips. The center of the ball is generally a hollow structure,
It is conducive to the rapid cultivation of nitrifying bacteria and purification of water quality. However, the quartz ball will make the water quality unstable and need to be replaced regularly.
Selection of filter media
Nowadays, there are many mixed filter media packages, which are actually not very practical, and we mainly choose one or two kinds of them. In the selection of the quality control of the filter media, some filter media broken seriously, powder serious do not choose, do not covet cheap choice of poor quality filter media. A good filter media can be replaced for several years.
Cleaning of the filter media
Filter media can be rinsed with clean water or disinfected with potassium permanganate. After a long time of use, when cleaning the filter media, you can choose to soak it in potassium permanganate water once every six months. However, during this period, to ensure that the nitrification system of the fish tank does not collapse, it is recommended to change half and half wash.
