Keeping your hot tub water clean and comfortable doesn’t require daily effort. A simple weekly routine helps prevent cloudy water, odors, and equipment issues before they start, making spa ownership much more enjoyable.
Start With Water Testing
Begin each week by testing your water. This gives you a clear picture of what your spa needs and prevents guesswork later.
Check:
pH: Aim for 7.2–7.8
Total alkalinity: Target 80–120 ppm
Sanitizer level: Follow the range recommended for chlorine, bromine, or salt systems
When these numbers are balanced, your sanitizer works properly and the water feels comfortable on your skin.
Clean and Check the Filters
Filters are essential for keeping debris, oils, and contaminants out of the water. Rinse them thoroughly with a hose each week to remove buildup. If they look greasy or clogged, a filter soak can help restore performance.
Clean filters improve circulation and prevent cloudy water.
Replace filters as recommended by the manufacturer or when they start to lose shape or effectiveness.
Adjust Sanitizer Levels
After testing, add sanitizer if needed. This step keeps bacteria and contaminants under control throughout the week, especially if the spa gets frequent use.
Make sure circulation is running so the sanitizer distributes evenly across the water.
Shock the Water Weekly
Even clear water benefits from a weekly shock treatment. Shocking removes oils, lotions, and organic waste that regular sanitizer can’t fully handle on its own.
This step:
Refreshes the water
Prevents dullness and odors
Helps maintain clarity
Shock is especially important after heavy spa use.
Spot-Check for Foam or Cloudiness
Take a quick look at the water surface. If you notice foam or haze, a small amount of clarifier or defoamer can help. These should be used sparingly and only when needed.
Foam or cloudiness often signals:
Dirty filters
High bather load
Imbalanced water chemistry
Wipe Down the Shell and Waterline
Finish your routine by wiping the waterline and shell with a soft cloth. Oils and residue tend to collect here, and removing them prevents buildup from re-entering the water.
This quick step keeps your spa looking clean and helps maintain water quality.
