⚙️ What it does

The SD60 is a sand filtration system, meaning:

\n
1. Pool water is pushed through a sand bed
\n
2. Dirt, algae, and debris get trapped in sand
\n
3. Clean water returns to the pool
\n
4. You periodically backwash the system to clean the sand
\n

👉 No cartridges, no media replacement every few weeks.

🧱 Build quality

\n
• Heavy-duty one-piece molded tank (no seams)
\n
• UV + corrosion resistant plastic
\n
• Large internal sand bed for better filtration efficiency
\n
• Designed for continuous seasonal use (hot climates included)
\n

👍 Key advantages

✔ Handles large pools (up to ~43k gallons turnover range)
✔ Very simple maintenance (backwash instead of replacing filters)
✔ Strong Pentair reliability (commercial-grade design philosophy)
✔ Good match for 24’ round / 24×12 rectangular pools
✔ Works well with salt systems (like AquaRite / PLC1400 setups)

⚠️ Real-world limitations

\n
• ❌ Requires correct pump sizing (undersized pump = poor clarity)
\n
• ❌ Needs proper backwashing every 1–3 weeks in heavy use
\n
• ❌ 1.5” plumbing limits flow upgrades unless valve is changed
\n
• ❌ Sand needs replacement every ~3–5 years for best performance
\n
• ❌ Takes significant space on equipment pad
