This Velda pond balance bacterial contains nitrifying bacterial cultures in freeze-dried form, and can be used to quickly create a natural balance in your pond. In a new pond, it takes four to six months before the micro-organisms and bacteria have sufficiently increased in number and there is a natural bacterial balance. The freeze-dried bacteria can be easily mixed with the soil or scattered in the water. If a pack of 50 ml bacterial is added to pond water, approximately 20 billion nitrifying bacteria will be subsequently produced within 24 hours. Although they are very tiny in size and invisible to the naked eye, these bacteria are essential to almost every form of life on earth.

• Volume: 1000 ml
• Suitable for 100000 L pond water
