Keeping Your Pool Water Crystal Clear – The Natural Way

As a homeowner in New Zealand, I love having a pool, but keeping the water clear without relying too much on chemicals can be a challenge. Fortunately, there are plenty of natural methods to maintain clean, healthy water while reducing the need for chlorine and other harsh treatments.

Here are some of the best natural ways to maintain a sparkling pool in Aotearoa.

1. Keep Your Pool Well-Circulated

Good water circulation is key to preventing algae and bacteria buildup. If your pump and filter system aren’t running efficiently, stagnant water can quickly become cloudy.

• Run your pump regularly: Aim for at least 6–8 hours per day, even in winter.
• Consider a solar-powered pool pump, available from New Zealand suppliers like Solar Group NZ, to reduce energy costs while maintaining circulation.

2. Use a High-Quality Pool Filtration System

Your pool’s filter is critical for removing debris and contaminants. A clogged or inefficient filter can cause cloudy water.

• Diatomaceous earth (DE) filters are highly effective and available from NZ pool retailers like The Pool Warehouse.
• Regularly clean your filter to ensure it’s working optimally. Sand filters should be backwashed every 1–2 weeks.

3. Maintain the Right pH Balance Naturally

New Zealand’s climate and water sources vary widely, and pH levels need to be balanced to prevent algae growth. Instead of using harsh chemicals, try these alternatives:

• Baking Soda (sodium bicarbonate) helps maintain alkalinity levels naturally. Look for it at supermarkets like Countdown.
• Vinegar can help deter algae and bacteria while adjusting pH levels gently.

4. Keep Debris Out with Regular Skimming and Vacuuming

Leaves, pollen, and dirt cause cloudy water if left unchecked. A simple daily routine can make all the difference:

• Use a pool skimmer daily to remove floating debris.
• Invest in a robotic pool cleaner, available from NZ retailers like Splash Pools, for a low-maintenance cleaning solution.

5. Harness the Power of Natural Enzymes

Enzymes break down oils, sunscreen, and organic matter that can lead to cloudy water or a scummy residue.

• Use natural enzyme-based pool treatments like those from BioGuard NZ.
• Add barley straw—a small bundle of barley straw (available from garden centres like Palmers) in your skimmer basket can naturally help prevent algae growth.

6. Use Plants and Natural Oxygenation for a Healthier Pool

Some pool owners in NZ are opting for natural swimming pools, which use aquatic plants to filter and clean the water.

• Consider creating a dedicated regeneration zone with native aquatic plants like harakeke (flax) and raupo (bulrush), promoting natural filtration.
• Visit WaterForce NZ for eco-friendly water filtration and aeration solutions.

7. Saltwater Pool Systems – A Natural Alternative

If reducing reliance on chlorine is your goal, a saltwater chlorinator could be a great alternative. These systems naturally produce chlorine from salt, providing gentler water quality.

• Available from NZ pool specialists like Pool & Spa Warehouse.

8. Cover Your Pool When Not in Use

A simple pool cover helps prevent debris from entering the water and slows down algae growth by blocking sunlight.

• You can find solar and winter covers at Kiwi pool suppliers such as Para Rubber.
