HTH 67121 is a diatomaceous earth (D.E.) filter aid supplied in a 10 lb container that restores filtration efficiency and improves pool water clarity. The powder forms a porous coating on D.E. filter grids after backwashing to trap extremely fine particles (approximately 2 to 6 microns). It contains amorphous silica, is compatible with all D.E. filters including saltwater systems, and is applied as a slurry mixed roughly 1 part powder to 10 parts water.
Diatomaceous earth filter aid, 10 lb powder; amorphous silica active ingredient; slurry application and dosage guidance included.
