Description The filter ball is made of fiber wire, which has better elasticity compared with traditional granular filter material. In the filtration process, the efficiency is high, the filter is fast, the dirt interception ability is large, and it is renewable, suitable for filtration of various water qualities. Features - Color: White.- Material: Fiber.- Size: 5.00X5.00X5.00cm/1.97X1.97X1.97 inch.- Filter balls to be easy to manage, lighter than sand filter media and it improved circulation and filtration, with lower filter pressure and higher flow rate.- Eliminate hauling and disposal of hundreds of pounds of sand.- The micro-suspensions that are not easily precipitated can be treated by adsorption to oil and other impurities.- Filter ball is with good elasticity, difficult to build, large gap, long working cycle, and small loss.- Being lighter and more efficient with good elasticity, not floating surface, large gap, long work cycle compared with the traditional steel filter material.Packing list: 1 pack x pool cleaning balls (200g)
