SAND/FILTER AID -  For Sand Filters, 
                        Works in Cartridge and D.E. Filters too!

An amazing product that temorarily coats the filter surface allowing the filter to quickly filter out even tiniest, the most difficult to filter particles.  The result is incredible clarity in a short amount of time. 

• Restores sparkling appearance
• Removes dead algae remains
• Helps remove discoloring matter, such as parcipiated metals
• Safe - contains natural microcellulose fiber

Sand/Filter AID is added through the skimmer (2-1/2 cups for typical inground pool size) after sand filter is backwashed.  The Sand/Filter Aid coats top of the filter bed and immediately begins capturing fine particles as they pass through the filter.  Sand/Filter Aid works so fast, the user must closely monitor the pressure gauge of the filter and perform a backwash at the normal "backwashing" pressure.  After backwashing, SAND/FILTER AID must be added again through the skimmer. 

SAND/FILTER AID can be added after each backwash cycle until the desired clarity and sparkle is acheived. 

SAND/FILTER AID can work in conjunction with other clarifiers such as PB ULTRA CLARIFIER or SEAKLEAR NATURAL CLARIFIER to further speed the clearing process and to acheive maximum water sparkle and clarity.
