Maintenance Tips

• Maintain proper water chemistry
  Use the ChemConnect™ dispenser and test water weekly to keep chlorine and pH balanced for safe, clear swimming.
• Run the sand filter efficiently
  Operate the included sand filter pump daily to circulate water and remove debris—longer runtime improves clarity and hygiene.
• Skim & vacuum regularly
  Use the surface skimmer to catch debris early and vacuum the pool floor weekly to prevent buildup and strain on the filter system.
• Protect the steel structure
  The galvanized steel walls are corrosion-resistant, but periodic inspection helps prevent rust and ensures long-term durability.
• Preserve the UV-resistant liner
  Avoid sharp objects and maintain water levels to prevent liner stress—its UV coating protects against cracking and fading.
• Keep it covered when not in use
  Use the pool cover to reduce debris, evaporation, and chemical loss, especially overnight or during off-season.
• Ensure proper installation & base
  A level, stable surface prevents wall stress and maintains the pool’s circular structure for long-term performance.
• Year-round care (semi-permanent design)
  This Hydrium model can stay up all year—clean, balance water, and winterize properly to extend lifespan.
