First, the selection of aquarium products:
1. A good activated carbon product is subjected to “activation treatment”. The so-called “activation treatment” means that the porosity of activated carbon is significantly improved during the manufacturing process to make it more absorbent. However, whether or not the product has been “activated and treated” with the naked eye is difficult to identify, and can only be determined based on the characteristics of the product.
2. There are many kinds of activated carbon products on the market. Many fish farmers who prefer to fish are difficult to distinguish between their good and bad. Some products are basically charcoal only and can not effectively remove the harmless spirit. This kind of products that look like charcoal on the outside are generally glossy, and it is better not to purchase. Please look for Laoshan Brand Activated Carbon. We used to have more than 30 years of experience. History.
3, when purchasing, please keep in mind that the smaller the particles, the better the effect. Because of its larger total external surface, the more pores there are. However, the particles must not be too fine to be powdered, so as to avoid the application of convenience and affect the filtration flow rate of the filter. It is generally preferred that the particle size be approximately 1 mm in diameter.
Second, the use and dosage of aquarium supplies:
1. Activated carbon can be used to remove suspended matter from the water, but its voids will be quickly obstructed by suspended solids, and the original result will be achieved. Therefore, it should be placed on the top of the filter cotton, so that after the filter cotton is first disposed of to remove the suspended matter in the water, the soluble harmless spirit of the filter cotton cannot be disposed by the activated carbon, but the activated carbon to prevent the particles from being too small The tail end of the filtered water flows into the aquarium and is also changed locally so that it can be replaced locally. It is best to place it as a second layer of filter data, and place other filter data such as biological filter balls, ceramic rings, etc. Under it.
2. Activated carbon is best placed in a mesh bag and then it is fastened. The bag filled with activated charcoal can be placed in an internal filter or placed in the drip filter's sink. When necessary, the voluntary local flow of water through the activated carbon, but in some cases this will add filter resistance and reduce its effectiveness. However, since the effect of activated carbon is very slow, it is advisable to use local water flow through the activated carbon filter so that it does not affect the filter's resistance. The benefit of this approach is that both aerobic and anaerobic bacteria can grow in the filter at the same time. The aerobic bacteria can perform oxidative synthesis, while the anaerobic bacteria synthesize nitrate into nitrogen in the anaerobic zone of activated carbon. Therefore, the activated carbon filtration data will change with the filtering nature of the chemical to the nature of the biological filtration.
3. Place the activated carbon in the fish tank of Yantai Aquarium Please pay attention to the most important point. Don't keep it in the filter. Although he has a small amount of ability to absorb harmless spirit, but after a long time, there will still be saturated time. Not only can not receive the spirit, but will release the harmless spirit, affect the water quality in the cylinder, many people keep fish for a long time, have to change the water, change the filter and other measures, but still down the cylinder, is this reason,
4, if it is constantly into the water, please note that one or two months to let him recover once, how to recover? Take out the activated carbon and rinse it in clean water. Then take the sun for two days and then rinse it with clean water.
5, after the ordinary medicine bath, put the activated carbon to adsorb the residual medicine, two days later took it in, do not exceed one week, place the status of the filter in the bottom can be.
6, in addition, activated carbon filter data in the aquarium there is another role. That is, when using an ozone generator, the ozone-containing water stream must be filtered through activated carbon to confirm that the filtered water does not have any ozone.
