Pool Filter Sand, HTH #20 Silica for Sand Filters, 50 lb Bag

Why Pool Owners Refill with HTH Filter Sand

• Washed and graded. HTH puts the sand through a washing and grading process so the filter bed traps dirt, debris and fine particles.
• #20 silica sand. The grade printed on the bag.
• Every sand filter. For residential and commercial pools using sand filters, saltwater included.
• Non toxic. As printed on the bag; see the dust warning below.

How to Change Pool Filter Sand

HTH defers to your filter's maker for the amount of sand and the change-out steps, so start with the filter manual. The usual job looks like this:

1. Turn off the pump, drain the filter tank and remove the multiport valve or top.
2. Scoop out the old sand and check the laterals for cracks.
3. Cover the standpipe, part fill the tank with water to cushion the laterals, then pour in the new sand to the level the filter manual gives.
4. Refit the valve, backwash, rinse, and return to filter.
