I have forty cm long, width of twenty, high grade of fourteen rectangular fish tank. Three ten cm koi. Every day at noon to feed a few grains of rice, the next day a small amount of feces removed with the net, there is no impurities in the water. But a few days there is fog water. Water is also used for precipitation, but the fish is not very lively. I didn't buy the filter. Would you say that the charcoal is a common wood burned after the formation of charcoal? How can I use to filter the water? Bamboo charcoal in the aquarium to sell it? How much is it?
Good activated carbon products are activated treatment, the so-called activation treatment refers to the manufacturing process, the porosity of activated carbon will be significantly improved, so that it has more adsorption. However, whether the product has been "activated" with the naked eye is difficult to identify, usually only based on the characteristics of the product to determine.In addition, remember when you buy smaller particles, the better the effect. Because the larger the total surface area, the more pores. But the particles can not be too fine powder, so as not to cause inconvenience to the use of the filter flow filter. Generally with a diameter of about 1mm diameter better.
There are many kinds of activated carbon products in the market, and it is very difficult for many aquatic animals to distinguish between them. Some products are simply charcoal, it can not effectively remove harmful substances, which looks like charcoal on the surface of the product, usually shiny, it is best not to buy.
Activated carbon has a strong physical adsorption and chemical adsorption ", can be certain organic compounds adsorption removal effect by using this principle, we can quickly and effectively remove harmful substances, the aquarium water odor and pigment and so on, so the water quality directly and rapidly improve.
