1. What is fiber ball? 

Fiber ball filter is spherical filter knotted by fiber,compared with traditional rigidity filter,has good elasticity,no floating, long working period and small head losses. In the filtering process, filter layer gap along the flow direction is becoming smaller, more accord with ideal filter material by big under small porosity distribution, thus forming the filter speed fast, cut pollution, large capacity, filtering effect is good, renewable repeatedly used and don't change entirely and save Labour, etc. 

2. How to use?

2.1 For the first use of new water, each carrier can treat 20-30 liters of water. It can be placed in the filter alone or thrown into the filter together with the mesh bag. For the old hydroponic bacteria, each carrier can treat about 10 liters of water. , When used in conjunction with other carriers, the dosage can be appropriately reduced.

2.2 When there is too much sewage, please wash it with clean water and re-use it, and add nitrifying bacteria. The normal service life is one year.
