Clear, balanced water protects your hot tub, makes every soak more comfortable, and helps your sanitizer do its job. In the Arizona East Valley, mineral-heavy fill water and windblown dust can make regular testing and filtration especially important.
Start With These Six Essentials
- Test regularly: Check your water before problems develop.
- Balance alkalinity and pH: Make one adjustment at a time, circulate, and retest.
- Maintain sanitizer: Follow the label for your chosen system, especially after heavy use.
- Keep the filter clean: Rinse, clean, and replace it on your manufacturer’s schedule.
- Watch your fill water: Hard water can affect balance, scale, and comfort.
- Refresh water when needed: Follow your manufacturer’s recommended change schedule.
A Simple Routine for Clean, Clear Water
Keep water care manageable by testing it regularly, running the filtration cycle recommended for your model, maintaining sanitizer according to its label, and refreshing the water on your manufacturer’s schedule. Make one chemical adjustment at a time, let the water circulate, and retest before adding more.
Use Marquis Chemistry Targets as Your Baseline
- pH: 7.4–7.6
- Total alkalinity: 80–140 ppm
- Calcium hardness: 150–250 ppm
Test total alkalinity before fine-tuning pH. Balanced alkalinity helps keep pH from swinging, while the right calcium hardness helps limit foaming and scaling. Use only products intended for your spa and follow the product label and your owner’s manual.
Arizona Hard Water: Start With the Fill
East Valley water can carry a substantial mineral load, so a fresh fill deserves extra attention. A pre-fill filter can help reduce sediment at the start. If you fill from a softened line, test calcium hardness after filling and bring it into your manufacturer’s target range rather than assuming the water is ready to heat.
Filtration and Sanitizer Work Together
Rinse and clean your filter on the schedule in your owner’s manual, and replace it when it will no longer come clean or shows damage. Keep circulation running as recommended for your model. Test sanitizer often—especially after heavy use, a dust storm, or a party—and adjust only according to the label for your chosen sanitizer system.
A strong “chlorine” smell is not a reliable sign that there is too much sanitizer. It can mean the sanitizer has reacted with contaminants. Test the water first, then use the corrective steps and products approved for your spa.
Health and Safety: Clear Water Is Not the Only Check
Water can look clear and still be out of balance. Proper sanitizer and pH help reduce the risk of germs associated with poorly maintained hot tubs, including hot-tub rash. If someone feels unwell after soaking, stop using the spa and seek medical advice.
When It’s Time to Change the Water
When water will not stay balanced or clear, follow your owner’s manual for a safe drain and refill. Do not direct spa water into streets, curbs, gutters, or storm drains; check your city’s current guidance before draining.

Quick Troubleshooting
- Cloudy water: Test sanitizer, pH, and alkalinity; clean the filter; confirm circulation.
- Foam: Check for lotions, detergent residue, or unbalanced hardness; retest before treating.
- Dust or debris: Remove debris promptly, clean the filter, and retest sanitizer after the event.
- Recurring odor: Test the water; follow your manufacturer’s corrective guidance rather than guessing.
