Natural Ways to Keep Your Pool Water Clear

Owning a pool in New Zealand is fantastic, especially during our warm summers, but keeping the water clear without relying on harsh chemicals can be a challenge. Many homeowners want a more natural approach, whether it’s to reduce chemical exposure, protect the environment, or save on costs. Thankfully, there are several effective ways to maintain crystal-clear water naturally.

1. Use a High-Quality Pool Filtration System

Proper filtration is the backbone of clean pool water. Your pool’s pump and filter should be running efficiently to remove debris and bacteria. Sand filters, cartridge filters, and diatomaceous earth (DE) filters are all good options. If you’re looking to upgrade, retailers like The Warehouse and Para Rubber offer various filtration systems suited to different pool sizes.

• Tip: Run your pool filter for at least 6–8 hours per day to help keep water clear.

2. Install a Natural Pool Skimmer

A natural skimmer works similarly to a standard mechanical skimmer but can be used without chemical additives. It removes leaves, insects, and other debris before they break down and introduce unwanted bacteria into your pool. You can find skimmers and pool maintenance equipment at Bunnings New Zealand or Mitre 10.

3. Add Beneficial Plants (For Natural Swimming Ponds)

If you’re open to transforming your pool into a more natural swimming pond, aquatic plants like lilies and reeds can filter impurities naturally. These plants absorb excess nutrients, preventing algae growth. Companies such as Palmers Garden Centre can guide you on suitable plant options.

4. Regularly Brush and Vacuum Your Pool

Dirt and algae can build up on your pool walls and floor, leading to cloudy water. Brushing the walls and floor regularly, along with vacuuming, helps prevent algae growth and keeps the water looking fresh. Manual pool vacuums and robotic cleaners are available from Pool and Spa Warehouse NZ.

• Tip: Invest in a robotic pool cleaner if you want an easy, energy-efficient way to keep your pool spotless.

5. Use Baking Soda for Algae Control

Baking soda is a natural and safe way to maintain proper pH balance in your pool. A sprinkle of baking soda can also help prevent algae growth by keeping alkalinity levels stable. You can find bulk baking soda at most supermarkets, such as New World or Countdown.

6. Consider a Saltwater Pool System

A saltwater pool operates with a salt chlorinator, which naturally produces chlorine in lower concentrations than traditional chemical treatments. This is a great alternative to manually adding pool chemicals while keeping the water clear and soft on the skin. Saltwater systems are available from Pope Pool Care and other local suppliers.

7. Use a Pool Cover

A simple yet powerful tool for maintaining water clarity is a pool cover. Covers prevent leaves, dirt, and debris from entering the water, reducing the strain on your filtration system. You can buy solar pool covers from Clark Rubber NZ or Trade Tested NZ.

• Tip: A solar pool cover also helps retain heat, reducing energy costs if you use a pool heater.

8. Explore UV and Ozone Pool Sanitation

UV and ozone pool sanitisation systems reduce bacteria and other contaminants without the need for excessive chemicals. A UV sanitiser uses ultraviolet light to neutralise bacteria, while an ozone generator injects ozone gas into the water to break down organic matter. You can explore options at Waterco NZ for sustainable pool treatment solutions.

9. Regularly Test Your Water Levels

Even without chemicals, keeping pH and alkalinity levels balanced is crucial for clear water. Testing kits are inexpensive and available from stores such as Torpedo7 and Rebel Sport. A well-balanced pool not only looks good but also prevents algae from forming.

10. Encourage Good Swimming Hygiene

Encouraging swimmers to shower before entering the pool can greatly reduce the introduction of oils, lotions, and dirt into the water. Simple habits make a big difference in overall water quality.

By combining these chemical-free approaches, you can maintain a clear and healthy pool naturally while ensuring a safe swimming experience for your family and friends. Whether you’re using a high-quality filtration system, maintaining your pool regularly, or harnessing the power of natural alternatives, there are plenty of great ways to enjoy pristine pool water—without the need for harsh chemicals.
