Which Hot Tub Chemicals Can Brave the Cold?

As winter sets in, hot tub enthusiasts must pay special attention to the care and maintenance of their beloved relaxation haven. While a hot tub can provide a warm sanctuary against the chilly temperatures, the chemicals and accessories used for water treatment also need careful consideration. Not all hot tub chemicals are built to withstand the frigid winter months, and choosing the wrong ones might lead to inefficiency or even deterioration. Let's dive into which hot tub chemicals are okay to leave outside during winter and which ones should find refuge indoors.

Winter-Ready Warriors: Chemicals That Brave the Cold

1. Chlorine-Based Sanitizers:

   • Chlorine is a robust sanitizer that can withstand colder temperatures. It effectively fights bacteria and algae, making it a reliable choice for winter hot tub care.

   • Ensure you use a stabilized chlorine product, as these are designed to resist degradation from UV rays, providing longevity even in outdoor winter conditions.

2. Bromine:

   • Bromine is another excellent sanitizer suitable for winter. It remains effective at higher temperatures, making it a popular choice for hot tubs.

   • Bromine tablets or granules are the preferred forms for winter use, offering a steady release of sanitizer over an extended period.

3. pH Balancers:

   • pH balancers, such as pH increasers and decreasers, are generally stable in cold temperatures. Maintaining the proper pH level is crucial for water balance and the overall effectiveness of other chemicals.

Seek Shelter: Chemicals & Accessories to Bring Indoors

1. Non-Stabilized Chlorine:

   • Unlike stabilized chlorine, non-stabilized chlorine compounds are more vulnerable to breaking down in sunlight. They are better stored indoors during winter to maintain their efficacy.

2. Algaecides:

   • Algaecides, while effective in preventing algae growth, may not fare well in freezing temperatures. Store them in a cool, dry place to avoid potential crystallization or degradation.

3. Enzyme Cleaners:

   • Enzyme-based cleaners are beneficial for breaking down organic contaminants in the water. However, they might lose their effectiveness if exposed to extreme cold. Bring them indoors to preserve their enzymatic activity.

4. Test Strips

   This is probably the most overlooked item on the list. You wouldn’t think that test strips would be affected by the cold, but they are! There would be no way of knowing, except, your readings will stop being accurate, adding a lot of frustration to your routine.

5. Any Liquids

   This is probably obvious to most, you do live in Canada after all. Cover cleaner, acrylic cleaner, filter cleaner, or any liquid hot tub chemical may not be effective after it’s been frozen, even after it’s been defrosted.

Winter Maintenance Tips for Hot Tub Chemicals:

1. Secure Storage:

   • Store your chemicals in a secure, dry, and cool place. A well-insulated shed or garage is ideal to protect them from extreme temperature fluctuations.

2. Regular Monitoring:

   • Throughout the winter, continue to monitor your hot tub water regularly. Adjust chemical levels as needed, even in the colder months, to ensure your hot tub remains a clean and inviting oasis.

By understanding which hot tub chemicals are winter warriors and which ones require a cozy indoor spot, you can keep your hot tub water crystal clear and ready for a dip even in the coldest weather. Winter in Alberta may be relentless, but with the right chemical care, your hot tub can stay resilient and inviting throughout the season.
