Filterballs Blu Advanced Filter Media are an alternative to filter sand. They require less backwashing, less pressure and can capture particulates as small as 5 microns. Filterballs are the evolution of pool filtration media!
1 cubic foot (~ 1 lbs) of FilterBalls Blu10 = 100 pounds of #20 silica sand
1/2 cubic ft (~0.5 lbs) of FilterBalls Minis = 50 pounds of #20 silica sand
Consumes less energy by operating at a lower working pressure
45% increased flow rate at lower pump speeds
Filters particulates smaller than 3.5 microns
Easy DIY installation and replacement!
Lasts 3-4 years and does not degrade like #20 filter sand.
Directions for start-up (Empty Tank, system off):
1) Add FilterBalls to tank. They are soft and can be easily moved around when filling.
2) Re-attach Multiport Valve or tank lid making sure the stand-pipe is properly attached and set to rinse for 2 minutes, backwash for 2 minutes and then set to filter mode.
3) Backwash again when pressure increases by 5-7 PSI.
