Getting Your Pool Water Ready for the First Time in New Zealand
Owning a swimming pool is a fantastic way to enjoy New Zealand’s warm summer months, but knowing how to treat the water properly from the start will save you time, money, and frustration down the track. If you’ve just installed a new pool or have filled it for the first time, follow these key steps to ensure safe, clean water for you and your family to enjoy.
1. Fill Your Pool with Clean Water
Before you begin treating the water, you’ll need to fill your pool. Most homeowners use town supply water, but if you’re using bore or rainwater, make sure to test it for impurities as these sources can contain minerals or contaminants that may affect water balance. If needed, you can get professional water testing done at Pool & Spa Warehouse or Bunnings NZ.
2. Test the Water Chemistry
Once your pool is full, the first step is to test the water’s chemical levels. You’ll need a test kit or test strips that measure:
- pH levels (ideal range: 7.2 – 7.6)
- Alkalinity (80 – 120 ppm)
- Chlorine or sanitiser levels
- Calcium hardness (ideal if you have a concrete or plaster pool)
You can purchase pool test kits from Mitre 10 or Poolwerx NZ. If you prefer, take a water sample to a local pool store for free professional testing and advice.
3. Balance the pH and Alkalinity
Balancing pH and alkalinity is crucial to maintaining comfortable, non-corrosive water. If either level is out of range:
- To raise alkalinity, add sodium bicarbonate (baking soda).
- To lower alkalinity, use muriatic acid or a pH-lowering chemical.
- To adjust pH, add pH increaser (sodium carbonate) or pH decreaser.
Many Kiwi retailers, like Spa & Pool Warehouse, offer water balance chemicals suited for various pool types.
4. Sanitise with Chlorine
Chlorine is the primary sanitiser that kills bacteria and prevents algae in your pool. If you’re using your pool for the first time, consider doing a shock treatment by adding a higher dose of chlorine to get rid of any organic contaminants before settling into regular maintenance levels.
Options include:
- Liquid chlorine: Fast-acting, but requires ongoing dosing.
- Chlorine granules or tablets: Convenient and slow-dissolving.
- Saltwater chlorination: If you have a saltwater pool, ensure your salt chlorinator is correctly set up and add pool salt as required.
You can find chlorine and other sanitisers at The Warehouse or local pool shops such as Pool & Leisure.
5. Add an Algaecide and Clarifier
To prevent algae from taking hold in your new pool, you may want to add an algaecide. This acts as an extra layer of protection, especially in New Zealand’s humid summer.
A clarifier can also help keep your water crystal-clear by clumping tiny particles together so that your pool filter can remove them more efficiently.

6. Turn on Your Pool Pump and Filter
Run your pool pump and filtration system for at least 24 hours straight after adding your initial chemicals. This ensures everything circulates properly and starts working efficiently.
- If using a sand filter, check that it’s clean.
- If using a cartridge filter, ensure it’s installed correctly.
- If needed, backwash the filter the next day to remove any trapped debris.
Regular maintenance of your filter and pump is essential for keeping your pool water clean. If you need help choosing the right filter, Maytronics NZ offers a variety of filtration options.
7. Monitor and Adjust Regularly
The first few days after filling your pool are crucial. Test the water daily and make slight adjustments as needed. Once your chemical levels stabilise:
- Test your pool 2-3 times a week.
- Clean out skimmers and vacuum the pool regularly.
- Maintain proper chlorine and pH levels to prevent future issues.
For ongoing maintenance supplies, places like Chemicals Direct NZ and Placemakers offer a variety of options.
Enjoy Your Pool!
Once your water is properly balanced and sanitised, you’re all set to enjoy your new swimming pool! Taking the right steps at the beginning means fewer headaches later on, so keep up regular testing and maintenance for a sparkling, healthy pool all summer long.
