1. Nano quartz balls can successfully breed nitrifying microorganisms in a short time, slow down the water flow, and make it easier for nitrifying microorganisms to adsorb on the nano quartz balls for reproduction. The more times it is used, the more obvious the effect. 2. Quickly remove harmful substances in the aquarium, such as nitrates, nitrites, ammonia, etc., while removing harmful substances by parasitic nitrifying microorganisms, it also has a certain adsorption effect, and can quickly remove harmful substances in the aquarium by physical means. 3. Efficient cultivation, high-temperature sintering production process, internal voids within 10-100 microns, very suitable for the parasitism of beneficial microorganisms such as aerobic nitrifying microorganisms and anaerobic nitrifying microorganisms. 4. It can stabilize the water quality, especially the pH value and GH value, on the existing basis of the aquarium, and will not cause changes in the pH value and GH value. 5. Super long life, dense structure, not easy to pulverize, can be used for a long time, easy to clean and reuse, and the life span is more than 2 years. 6. High-density pores bring more surface area, providing a good place for the attachment and reproduction of nitrifying microorganisms.
