Filterballs Blu Advanced Filter Media Minis are an alternative to filter sand. They require less backwashing, less pressure and can capture particulates as small as 10 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.
