Winnipeg winters are legendary—and so are the challenges of keeping your hot tub or pool water sparkling clean when draining and refilling simply isn’t an option. But with the right routine and winter-ready chemicals, you can keep your water healthy and inviting all season long—no draining required.
Why ‘No Water Exchange’ Matters…
Subzero temperatures, frozen pipes, and snow-packed yards make water changes risky or impossible during Manitoba’s coldest months. But that doesn’t mean you have to compromise on water quality. With the right steps, your spa, swim spa and plunge pool can thrive through the harshest winter.
Essential Winter Water Care Tips:

1. Test Your Water Weekly:
- Cold weather slows chemical reactions, so regular testing is more important than ever.
- Use a high-quality test kit, or bring a water sample to Aqua-Tech for a free test. Can’t make it in? Text a photo of your 5-way test strip to 204-817-8238, and our experts will reply with personalized water balance recommendations.
2. Prioritize Water Balance:
- pH: Keep between 7.4–7.6 to prevent corrosion (low pH) or scale buildup (high pH).
- Calcium Hardness: Aim for 100–200 ppm in hot tubs to protect equipment.
- Alkalinity: Maintain 125–150 ppm for stable pH.


3. Shock Regularly:
- Regular shocking oxidizes contaminants that build up when water isn’t replaced.
- Top choices: SpaGuard Rapid Action Shock Tabs, Trio #2 Weekly Pouch, or Mineraluxe Oxygen. These blended products deliver powerful cleansing, clarifying, and softening—all in one.
4. Use Winter-Grade Chemicals:
- Choose products specifically designed for cold climates—Aqua-Tech stocks the best hot tub chemicals in Winnipeg.
- Look for winter-labeled, fast-dissolving formulas for hassle-free care.


5. Prevent Biofilm & Scale:
- Prevent Biofilm & Scale
- Add a weekly enzyme and anti-scale treatment to stop buildup before it starts.Clean filters monthly—even with less frequent use.
6. Circulate Water Daily:
- Run your pumps as much as possible to prevent freezing and keep chemicals evenly distributed.
- Check your hot tub’s FILTER CYCLES section and program for maximum filtration.
- If equipped, activate freeze-protect mode for extra peace of mind.


7. Cover Up:
- Invest in a high-quality, insulated cover to retain heat and keep debris out.
- Regularly clear off ice or snow to protect your investment.
