How to Maintain Your Mineral Pool Over Winter
As the temperature drops and your pool gets used less frequently, it's important not to neglect your pool maintenance routine. Winter can be a challenging time for pool care, but with a few simple steps — and the right products like Mineral Swim — you can keep your mineral pool clean, healthy and ready for action come spring.
Whether you choose to keep your pool open or cover it during the cooler months, proper winter care ensures you protect your investment and avoid costly repairs or cleaning later.
Why Winter Pool Care Is Still Important
Even if you’re not swimming, your pool water still needs attention. Cold weather, rain, falling debris, and reduced sunlight can all impact water quality. Without regular care, your pool may develop algae, experience water imbalance or cause damage to your pool equipment.
Regular winter maintenance helps to:
Maintain water balance and clarity
Prevent algae and bacteria growth
Protect your pool equipment and interior surfaces
Save time and money on springtime clean-ups
Step-by-Step Guide to Winter Mineral Pool Maintenance
1. Start with a Deep Clean
At the start of winter, give your pool a thorough cleaning:
Skim leaves and debris from the surface
Empty skimmer baskets and clean the filter
Brush the walls and floor to remove build-up
Use a Dolphin robotic pool cleaner to vacuum dirt and debris
Keeping your pool clean reduces the risk of algae and ensures water clarity throughout the off-season.
2. Balance Your Water Chemistry
It’s vital to maintain the correct water balance over winter, even when your pool isn’t being used. This includes:
pH level: Aim for a range of 7-7.2 for fibreglass and 7.2-7.6 for concrete
Total Alkalinity: Keep within 80–120 ppm
TDS level: 3500-4500 ppm
Top up your pool with Mineral Swim Dead Sea Minerals to maintain the appropriate levels of chlorine in your pool to keep your pool water hygienic and safe, and improve water clarity, making maintenance easier all year round.
3. Reduce Filtration Time
You can reduce your pump and filtration run time to 2–4 hours per day during winter. However, ensure water continues to circulate daily to prevent stagnation.
4. Cover Your Pool (Optional but Recommended)
Using a pool cover during winter helps:
Reduce water evaporation
Keep out leaves and debris
Limit algae growth by blocking sunlight
A properly fitted, UV-stable pool cover will reduce your cleaning workload and support water balance.
5. Shock the Pool if Needed
If your water becomes cloudy or develops a strong odour, a winter shock treatment can help. Choose an oxidising product that’s compatible with Mineral Swim systems to remove organic contaminants and maintain sparkling water.
6. Check Your Equipment Regularly
Inspect your pool equipment every few weeks:
Clean the filter and skimmer baskets
Check the pump and chlorinator for blockages or wear
Inspect the Hydroxinator for any signs of mineral scaling
By catching issues early, you can avoid expensive repairs down the track.
7. Maintain Water Level
Over time, water can evaporate or overflow from rainfall. Check that your water level stays halfway up the skimmer opening to ensure proper circulation and filtration.
