Keeping Your Pool Water Clear the Natural Way
Owning a pool in New Zealand is a fantastic way to enjoy the warm summer months, but keeping the water clean and clear can sometimes feel like a full-time job. Many pool owners, myself included, want to reduce their reliance on harsh chemicals and instead use more natural methods to maintain crystal-clear water. If you’re looking for ways to keep your pool water pristine without relying solely on chlorine and other chemicals, here are some effective natural solutions.
1. Maintain Proper Water Circulation
Good water circulation is essential for a healthy pool. Stagnant water can become a breeding ground for algae and bacteria, so running your pool pump for the right amount of time each day is crucial. The recommended time can vary depending on the size of your pool and the climate, but many New Zealand pool retailers suggest running the pump for at least 6–8 hours per day during summer.
Where to find advice:
Retailers like Pool & Spa Warehouse NZ offer advice on pump efficiency and maintenance to keep your water moving cleanly.
2. Use a Pool Cover
Living in New Zealand means dealing with a mix of weather conditions, from hot sunny days to unexpected downpours. A pool cover helps keep out debris like leaves and dirt, which can introduce bacteria and make the water cloudy. It also reduces evaporation, which helps maintain chemical balance naturally.
Tip: Look for solar pool covers, which not only keep debris out but also help heat your pool naturally. Check out The Cover Company NZ for options.
3. Regularly Balance the Water pH
Even if you’re cutting back on chemicals, it’s still important to keep your pool’s pH balanced. The ideal pH for a pool is between 7.2 and 7.6. Too high, and algae can grow faster; too low, and the water can become corrosive. Using natural alternatives like baking soda to raise alkalinity or vinegar to lower it can help maintain the balance without harsh pool chemicals.
Where to test your water:
Stores like Bunnings NZ sell DIY pool testing kits that can help you monitor your pH levels at home.
4. Use Natural Enzymes and Baking Soda
Adding natural enzymes to your pool can help break down organic matter such as sunscreen, oils, and plant debris. These enzymes work by speeding up the decomposition process, preventing cloudy water and reducing the need for additional chemicals.
Baking soda is also a fantastic natural way to manage pool alkalinity—it helps stabilise pH levels and keeps the water softer for swimming. You can find bulk baking soda at Bin Inn NZ for a cost-effective solution.
5. Keep Your Pool Filter Clean
Your pool filter plays a crucial role in keeping the water clear. Whether you use a sand filter or a cartridge filter, regular cleaning is essential to ensure it continues working effectively. A clogged or dirty filter can lead to poor water circulation and buildup of debris.
Tip: Backwash sand filters at least once a month in summer and clean cartridge filters regularly with a hose. If your filter needs replacing, check out Para Rubber for pool maintenance supplies.
6. Add Plants and Shade Around the Pool
Having some shade around your pool can significantly impact water clarity by reducing the amount of direct sunlight hitting the surface. Algae thrive in warm water, so minimising sun exposure can help reduce algae growth naturally. Planting trees or installing shade sails can be a great way to provide natural cover.
Where to get shade solutions:
Check out Shade Systems NZ for shade ideas suited to New Zealand conditions.
7. Try Hydrogen Peroxide as an Alternative to Chlorine
Hydrogen peroxide is a great natural oxidiser that can help keep pool water clear without the strong chemical smell of chlorine. It’s safe to use in pools and breaks down into water and oxygen, making it an eco-friendly alternative. However, if using hydrogen peroxide, you will need to pair it with a UV or ozone system for best results.
Where to source hydrogen peroxide:
Online retailers like Supreme Health NZ may stock high-grade hydrogen peroxide suitable for pool use.
8. Introduce Beneficial Bacteria
Just like natural ponds, pools can benefit from the introduction of beneficial bacteria that help break down organic matter and reduce algae growth. This is a great way to naturally balance the water and improve clarity without adding harsh chemicals.
Where to find bacterial pool treatments:
New Zealand pool suppliers such as Eco Pool Solutions NZ specialise in natural pool cleaning methods.
9. Use a Robotic Pool Cleaner
While not a completely “natural” solution, using a robotic pool cleaner reduces the need for excessive chemicals by keeping your pool floor and walls free of build-up. These devices operate efficiently and can be a great investment for long-term pool maintenance.
Where to buy:
Maytronics NZ offers a range of robotic pool cleaners designed for New Zealand conditions.
A Natural, Healthier Pool
Keeping your pool water clear without relying heavily on chemicals is completely achievable with the right maintenance routine and natural methods. By maintaining circulation, balancing the pH, using natural cleaning agents, and keeping up with regular upkeep, you can enjoy a crystal-clear pool that is both eco-friendly and healthy for your family.
