How to Eliminate Hot Tub Bacteria According to Industry Experts

There’s nothing better than slipping into a hot tub at the end of a long day. But unfortunately, the same warm and humid environment that makes a spa so inviting is also ideal for bacteria to grow. If left untreated, bacteria can cause cloudy water, skin irritation, or even illness. 

The good news: with consistent care and a few simple practices, you can eliminate hot tub bacteria, leaving the water safe, clean, and ready to enjoy year-round. 

Inspect and Monitor Your Spa Regularly 

A quick inspection is often all it takes to catch bacterial problems early. Watch for: 

• Cloudy or discoloured water 
• A slimy film on surfaces 
• Unpleasant or sour odours 

If you notice any of these warning signs, it’s time to act fast with cleaning and water treatments (keep reading). 

Start with an Easy but Consistent Maintenance Routine 

Regular upkeep is necessary for all hot tubs. Start by wiping down the underside of your hot tub cover, the filter housing, and the tub shell with a mild bleach solution or spa-safe cleaner. Replace the cover if it becomes waterlogged, since damp insulation can harbour bacteria. 

Just as important, always test sanitizer levels before and after use. Chlorine, bromine, or other disinfectants only work if they’re maintained at the correct levels. 

Maintain and Change Filters 

Your filter is essential for trapping and removing bacteria and debris. If your filter is more than a year old, it’s usually best to replace it. For filters still in good condition, soak them overnight in a manufacturer-approved cleaning solution diluted with water, rinse thoroughly, and reinstall. 

Shock the Water When Needed 

Over time, lotions, body oils, and organic material mix with sanitizers and create combined available chlorine (CAC), which is far less effective at killing bacteria. A shock treatment resets your water by raising sanitizer levels about ten times higher than normal. 

To keep your spa safe, shock: 

• Weekly for regular use 

• After heavy use (such as hosting guests) 

• Whenever CAC levels exceed 0.5 ppm 

Remember to use safety precautions and never enter the water until sanitizer levels return to normal. 

Run the Pump! (It’s the Heart of Your Tub) 

Still water is where bacteria thrive. Run your hot tub pump continuously if possible, or set a timer so water circulates several times per day. Be sure to clean jets and plumbing lines as part of your routine so bacteria can’t build up in hidden areas.
