One Jin net pocket 23 * 13CM three Jin and five Jin net pocket 33 * 24CM

The diameter is about 2CM, packed in a bag, there are black spots on the glass ring which are sticky dust during firing, and it will not affect the use.

Glass ring, also known as biological ring or ceramic ring, is a very economical and efficient filter material, generally made of quartz sand fired, porous, large surface area, suitable for a large number of nitrifying bacteria living, is an indispensable filter material for fish farming, because it is used for nourishing bacteria, it does not need to be replaced frequently. Basically, it does not need to be ignored when it is put down. If the pores are blocked for too long, it can be cleaned with clean water and continued to use, of course, if conditions permit, it will be changed once every half a year. If you change the total amount of 1/2 each time, you can leave half of the old ring and half of the new ring. Remember, the newly bought ring must be washed with clean water.

Application Field: filter quartz glass ring products are suitable for aquarium, freshwater fish tank, seawater fish tank, fish pond, aquaculture, tap water and other industries, especially the biochemical filtration system of aquarium. Better use effect with activated carbon and biochemical ball.

Characteristics: this precision biological filter material is made of many air chamber ceramics by special high temperature burning, forming micro pores 0.1~100, which can cultivate high-density good qi and anaerobic nitrifying bacteria. It can reproduce a large number of harmful chemicals such as prebiotics and nitrous acid in a short period of time, reduce the production of moss, algae and germs, strengthen the immunity of fish, accelerate the balance of ecology, and create excellent clear water quality.

The filtered quartz ceramic ring is made of natural silicate raw materials sintered at 1300 ℃, with stable chemical properties, completely in line with the chemical environment of microbial primitive life, and has unique porous structure, the unit surface area is 6-9 times higher than that of common biochemical rings, with high permeability. Aerobic nitration and anaerobic denitrification can be carried out simultaneously to make the water quality more stable, which is one of the good biological filter material.
