Too Hot to Handle? Keep Your Hot Tub Happy in Summer Heat

How to protect your spa from damage, save money on chemicals, and enjoy a better soak, right through the hottest days of summer.
When the sun’s blazing and the temperatures rise, most people focus on cooling off. But if you own a hot tub, summer brings a different set of challenges—ones that can cost you time, money, and comfort if you’re not prepared.

Here’s what every spa owner should know about hot tub maintenance during Ontario’s heat waves—and how Main Street Pool & Spa in Uxbridge can help you stay cool and stress-free.

☀️ Summer Heat = Spa Stress
High heat doesn't just affect your comfort; it affects your spa's internal systems and water chemistry too.

If your spa is left running or covered for long periods in the summer:

• The water can overheat (especially in full sun)
• Chemical levels drop faster
• Bacteria can build up
• Filtration and pumps work harder

Result? Cloudy water, bad smells, and expensive repairs—unless you take some simple steps to care for your spa.

3 Quick Tips to Keep Your Hot Tub Healthy

1. Get Your Water Tested Weekly (It’s Free!)
When it’s hot out, chemical levels change fast, especially if you’re using your spa more or leaving it covered. Testing your water at least once a week ensures:

• Your sanitizer is balanced (chlorine or bromine)
• pH and alkalinity stay in a safe range
• You’re not wasting money on the wrong fix

Main Street Pool & Spa offers free spa water testing all summer long. Just bring in a sample and we’ll do the rest.

2. Adjust Your Chemical Routine for Summer
Hot weather = fast chemical evaporation.

We recommend:

• Testing more often (2x/week in a heat wave)
• Using Dazzle® spa chemicals, which are designed for Canadian climates and high-use periods
• Lowering your set temperature if the water feels too hot—this saves energy and helps with clarity
• You can also add a spa cover, umbrella or use your cover’s reflective underside to block excess heat.

3. Use SmartTub™ to Save Energy and Stress
If your Sundance Spa has SmartTub™ technology, you're in luck.

You can:

• Turn your temperature down remotely on hot days
• Use “Sleep Mode” during mid-day peak hours
• Get alerts and reminders if your water chemistry changes
• Automatically track when you last balanced your water

💡 Many Sundance® 880 and 780 models now include SmartTub—or it can be added as an upgrade.

Bonus: Is Your Spa Working Too Hard?
If your water’s cloudy, smells strange, or feels sticky, you may be overworking your system.

We recommend a quick service check if:

• You haven’t changed your filters in 6+ months
• You see foaming or white residue
• Your water level is lower than usual
• Your SmartTub app says “Needs Attention.”
• We offer on-site inspections and tune-ups for all Sundance® hot tubs in the Durham Region.
