What to Look for in Pool Filter Sand
Sand Specifications
Quality pool filter sand should meet specific criteria for effective filtration:
- Grain size: #20 silica sand (0.45-0.55mm diameter)
- Angularity: Sharp, angular grains trap debris better than rounded sand
- Purity: Free from clay, silt, and organic matter
- Standards compliance: Look for ANSI/NSF certification
Warning: Never use construction sand, play sand, or sandbox sand in pool filters. These contain fine particles that will cloud your water and potentially damage your filter system.
How Much Sand You Need
Sand filter capacity varies by size:
- 16-inch filter: 150 lbs (3 bags)
- 19-inch filter: 200 lbs (4 bags)
- 22-inch filter: 300 lbs (6 bags)
- 24-inch filter: 350 lbs (7 bags)
Check your filter manufacturer's specifications for exact amounts, as overfilling can reduce filtration efficiency.
Alternatives if Walmart is Out of Stock
Other Retailers
If your local Walmart doesn't have pool filter sand in stock, try these alternatives:
- Home Depot: Carries multiple brands year-round
- Lowe's: Good selection with competitive pricing
- Pool supply stores: Leslie's, Pinch A Penny for premium options
- Hardware stores: Local shops often stock seasonal pool supplies
Filter Media Alternatives
Consider these alternatives to traditional sand that may offer better filtration:
- Filter glass: Recycled glass media filters smaller particles (down to 5 microns vs sand's 20 microns)
- Zeolite: Natural mineral that filters to 10 microns and has ammonia-removing properties
- FilterBalls: Polyester fiber balls that replace 50 lbs of sand and filter to 10 microns
When to Replace Pool Filter Sand
Most pool professionals recommend replacing sand every 3-5 years, but several factors indicate it's time for replacement:
- Water clarity issues despite proper chemical balance
- Shorter time between backwash cycles
- Difficulty maintaining proper water chemistry
- Sand clumping or channeling visible during backwash
Regular maintenance extends sand life significantly. Backwash when pressure gauge reads 8-10 psi above clean starting pressure, and perform monthly rinse cycles to remove fine debris.
Installation Tips
When installing new filter sand from Walmart:
- Turn off pump and drain filter tank completely
- Remove old sand carefully to avoid damaging laterals
- Inspect and clean filter laterals and manifold
- Add water to cover laterals before adding sand
- Pour sand slowly around standpipe to prevent damage
- Level sand surface and reassemble filter
- Run initial backwash cycle for 2-3 minutes
Safety reminder: Always follow lockout/tagout procedures when working on pool equipment, and never work on electrical components while wet.
