Water Care Guide

Keeping the water in your outdoor whirlpool clean isn't difficult if you follow a simple routine. This guide walks you through everything you need for healthy, crystal-clear water. This guide provides general information only. Always follow the manufacturer manual for your specific model and the instructions on your chosen water-care products. Water chemistry depends on local water conditions and usage.

Why Proper Water Care Matters

Clean, balanced water protects the skin, keeps the whirlpool hygienic, prevents scale and corrosion, and ensures the massage pumps work efficiently. Good maintenance also reduces long-term operating costs.

Chemical Safety Checks

  • Always follow the instructions on the chemical packaging and your manufacturer manual.
  • Never mix chemicals together. Add products to water separately.
  • Store chemicals out of reach of children and away from heat/moisture.
  • If irritation, strong odor, or unusual water conditions occur, stop use and consult a professional.

Weekly Water Care Routine

  • Test the water 2–3 times per week (pH 7.0–7.6, balanced alkalinity)
  • Adjust pH if values are outside the recommended range
  • Maintain disinfectant levels according to manufacturer instructions
  • Shock-treat once a week to remove organic residues and keep water fresh
  • Run circulation for 15–20 minutes after adding any product

Filter Care

  • Rinse filters every 1–2 weeks
  • Deep-clean with a filter solution monthly
  • Replace filters as recommended by your whirlpool manufacturer

Refreshing the Water

  • Drain and refill every 3–4 months (more often with heavy use)
  • Clean the inner surfaces with a whirlpool-safe cleaner before refilling
  • After adding fresh water, rebalance and disinfect immediately
