【Product features】
This product adopts multi-layer coating technology, and the oxygen release time is up to 6-8 hours. It is mainly aimed at alleviating hypoxia in summer, increasing oxygen at the bottom of ice sealed pool in winter, cage culture, etc. It has the characteristics of less throwing number of times, high oxygen content and long oxygen release time. Due to long-time oxygen release, it can reduce ammonia nitrogen, nitrite, hydrogen sulfide and other toxic and harmful substances in water body, so as to save time, labor and energy cost saving and other purposes.
【Main purpose】
1 . Improve the bottom around the feeding table, induce feeding.
2. It can be used in summer with high temperature days, and can release oxygen for 6-8 hours, to prevent odor proof bottom and black bottom.
3. Low temperature continuous oxygen release for10-12 hours is used to increase oxygen under ice in winter, such as net cage,fish overwintering and sea cucumber.
【Usage and dosage】
1 . Daily management: 200g-250g per mu per meter water depth( China metrology unit:1 mu=667 square meters), throwing around the feeding table.
2. Deterioration of water quality: 200- 600g per mu per meter water depth are used to improve bottom quality and water quality.
3. Polluted ice after snow: 600 ~ 900g per mu per meter water depth.
4. Help to survive the winter smoothly: increase oxygen under the ice, punch and put in once every 15 ~ 30 days, 200g per mu permeter water depth each time.
