Alum

Dual purpose HASA Alum may be used as an additive to sand filters to improve filtration or can be applied directly to the pool as a floc.

Key Features & Benefits:

• Traps Particles: When added to a sand filter, Alum coats the filter bed and traps smaller particles that the sand alone cannot.

• “Floc” The Pool: When severe water clarity issues occur, it may be easier to “floc” the pool.  This process drops the suspended particles to the bottom of the pool which are then vacuumed to waste, rather than filtering.

• Two Ways To Use: Can be used as an additive in the sand filter or by broadcasting it all over the surface of the pool by flocculation.

Dosing Instructions:

• Sand Filter Aid: 1/2 cup to skimmer while pump and filter is running

• Floc: broadcast over surface of pool 2.5-5 lbs for 10,000 gals of water (Refer to detailed instructions on our website)
