Best Way To Keep Pool Water Clear Naturally

Why Keeping Your Pool Water Clear Naturally Matters

As a New Zealand homeowner, having a crystal-clear pool is essential for both aesthetic appeal and maintaining a healthy swimming environment. Many pool owners rely on chemical treatments like chlorine to keep their water clean, but natural methods can be just as effective while being safer for your skin, equipment, and the environment.

If you’re looking for ways to keep your pool water clear naturally, you’re in the right place! In this blog, we’ll explore the best natural pool maintenance practices and where you can find the right products here in New Zealand.

1. Maintain Proper Filtration and Circulation

One of the simplest and most natural ways to keep your pool water clean is by ensuring your filtration system runs efficiently. Good circulation helps prevent algae and bacteria buildup while distributing natural cleaning agents evenly throughout the water.

Run your filter for at least 8 hours per day: This ensures adequate movement and keeps debris from settling.
Clean your filter regularly: Whether you have a sand filter, cartridge filter, or a natural water filtering system, keeping it clean is crucial.
Consider a natural filtration system: Companies like Eco Pool Solutions NZ offer eco-friendly pool filtration options that reduce the need for harsh chemicals.

2. Use Baking Soda to Maintain pH Balance

Baking soda is a fantastic natural alternative to harsh pool chemicals. It helps stabilize pH levels, reducing murkiness and preventing algae growth.

How to use it: Add about ½ cup of baking soda per 10,000L of water to help with pH regulation. Make sure to test the levels before adding more.
Where to buy: You can find bulk baking soda at New Zealand stores like Bin Inn or Countdown in larger quantities.

3. Use a Pool Cover to Prevent Debris

A pool cover is an easy way to keep leaves, insects, and other debris out of your pool, reducing the need for constant cleaning and maintenance.

Invest in a high-quality pool cover: Look for solar pool covers, which also help heat your pool naturally while keeping it clean.
Where to find one: Check out Kiwi retailers like Para Rubber for a range of pool covers that fit different pool sizes.

4. Add Plants and Natural Minerals

There are natural mineral-based solutions and pool-friendly plants that help keep your pool water balanced.

Magnesium salts: Acting as a natural clarifier, magnesium can improve water clarity while being gentle on the skin. Many New Zealanders use magnesium pool systems to create softer, clearer water. Look for suppliers like Maytronics NZ.
Water plants around pool areas: While you won’t place them inside your swimming pool, certain plants like ferns and reeds near the pool can absorb excess nutrients that feed algae.

5. Regularly Skim, Brush, and Vacuum

Keeping up with simple daily or weekly maintenance makes a huge difference in keeping your water crystal clear.

Skim debris daily: Remove leaves, insects, and other floating debris early before they sink.
Brush pool walls and floor once a week: This prevents algae and calcium buildup.
Vacuum the pool regularly: Whether using a manual vacuum or a robotic cleaner, this helps remove buildup that brushing alone can’t reach.

6. Use a Natural Clarifier Like Seashells

Crushed seashells contain calcium carbonate, which can naturally help clear up cloudy pool water. Many Kiwi homeowners have experimented with adding filtered seashell gravel to their pool filters for a minor but effective boost.

You can find crushed shells at local supply stores like Mitre 10 for landscaping but ensure they are thoroughly washed before use.

7. DIY Natural Pool Cleaning Solutions

If you prefer to avoid store-bought clarifiers, there are some simple homemade remedies you can try:

White vinegar for mould/algae: Mix one part vinegar with three parts water and scrub problem areas around the pool edges.
Lemon juice for calcium buildup: Rub fresh lemon juice on calcium deposits and scrub lightly with a brush.

Both methods are safe and won’t harm your pool’s water chemistry.

8. Keep an Eye on Rainwater

New Zealand’s weather can be unpredictable, and heavy rainfall can throw off your pool’s chemical balance, leaving it cloudy or green.

Use rainwater wisely: While it’s great for topping up water, too much can dilute essential balancing minerals.
Check pH and alkalinity after rain: Test your pool water after a heavy downpour and adjust naturally with baking soda or magnesium salts if needed.

You can purchase affordable pool test kits online through retailers like Pumps & Filters NZ.

9. Consider a Natural Pool Conversion

If you’re looking for a long-term natural solution, turning your pool into a natural swimming pond might be an option. These pools use biological filtration systems with aquatic plants rather than chemicals.
