1. What is the ideal temperature for a hot tub?
Most users prefer 100°F–104°F (37.7°C–40°C). For children or long soaking sessions, 98°F–100°F is recommended.
2. How often should I change my hot tub water?
Generally every 3–4 months, depending on usage and water quality. 6-12 months with Salt system.
Use First Step after every refill
3. How often should I clean the filters?
Rinse weekly, deep-clean monthly, and replace filters every 12–24 months.
4. Do I need chemicals for my hot tub?
Yes. Essential chemicals include:
- Sanitizer (chlorine or bromine)
- pH balancer
- Alkalinity adjuster
- Refresh
- Sparkle Plus
- Protect
5. What’s the difference between chlorine and bromine?
- Chlorine: works fast, strong sanitizer, lower cost.
- Bromine: gentler on skin, works better in hot water, lasts longer, higher cost.
6. Can I use my hot tub in winter?
Absolutely. Hot tubs work well in cold climates as long as they are properly insulated and maintained.
7. How long can I safely stay in a hot tub?
20–30 minutes at normal temperatures (100–102°F). Shorter times at 104°F.
8. Can children use a hot tub?
Yes, with supervision. Limit temperature to 98°F and sessions to 10–15 minutes.
9. What maintenance is needed for a hot tub?
Basic tasks include:
- Test water 2–3 times weekly
- Clean filters regularly
- Check water levels
- Drain & refill seasonally
- Inspect the cover and jets
10. How long does a hot tub last?
Quality hot tubs typically last 10–20 years with proper care.
11. How much does it cost to run a hot tub per month?
Most modern, energy-efficient tubs cost $20–$50 per month, depending on climate and usage.
12. Can I put a hot tub on a deck?
Yes, but the deck must be structurally reinforced to support the weight (often 3,000–5,000+ lbs when filled).
13. Do I need an electrician to install a hot tub?
For 240V models, yes—professional installation is required.
110V plug-and-play tubs do not require an electrician.
14. Why is my hot tub water cloudy?
Common causes include:
- Dirty filters
- Low sanitizer levels
- Body oils, lotions, or soap residue
- High pH or calcium levels
15. How do I eliminate foam in my hot tub?
Foam is usually caused by body oils, residue, or too many dissolved solids. Use:
- Foam Away (quick fix)
- Water change + filter cleaning (long-term fix)
16. Can I use bath oils or bubble bath in my hot tub?
No. They can clog filters, interfere with chemicals, and create excessive foam.
17. Should I keep my hot tub cover on when not in use?
Yes. It helps maintain heat, keep out debris, and save energy.
18. How often should I replace my hot tub cover?
Typically every 3–5 years, depending on climate and use.
19. What’s the difference between a hot tub and a spa?
They are often used interchangeably, but “spa” can also refer to built-in, in-ground systems, while “hot tub” usually means portable, above-ground units.
20. Can I use a hot tub if I'm pregnant?
Consult your doctor first. Most medical professionals advise avoiding water over 100°F during pregnancy.
21. What is an Ozonator and benefits?
An ozonator in a hot tub generates ozone (
) gas, a powerful oxidizer, to sanitize the water by destroying bacteria, viruses, and organic contaminants like lotions and oils, reducing the need for chemicals like chlorine or bromine and keeping the water cleaner, clearer, and smoother. It enhances sanitizer effectiveness, breaks down unpleasant byproducts (chloramines), and helps clump dissolved solids for easier filter removal, resulting in less skin/eye irritation and odors. All QCA Spas come with Ozone Natural Water Sanitizing System, unless have a Salt Fresh System.
· Reduces chemical use: Less chlorine/bromine needed, but some residual sanitizer is still required.
· Improves water quality: Makes water clearer, softer, and less irritating to skin and eyes.
· Eliminates odors: Destroys odor-causing contaminants and chloramines (combined chlorine).
· Aids filtration: Causes total dissolved solids (TDS) to clump, making them easier for the filter to catch.
· Natural process: Ozone is a natural element, and the gas breaks down harmlessly

23. Is there a specific area to bring in the electrical wiring?
No, QCA Spas does not have a designated area for bringing in electrical wiring. However, the wiring should be long enough to reach the front of the spa, underneath the control panel.
If you are going to bring in wiring up through the concrete please call your local QCA Spa dealer to get exact location.
