Natural Ways to Keep Your Pool Clean

Pool maintenance doesn’t have to mean dumping in loads of chlorine and harsh chemicals. If you’re looking for a more natural approach, good news—there are ways to keep your pool clean without turning it into a chemical soup. Let’s break it down.

Use a Pool Cover

This one’s simple. Covering your pool when you’re not using it helps prevent leaves, dirt, and random debris from getting in. Less junk floating around means fewer bacteria and algae forming, making your job a whole lot easier. You can find good pool covers at places like Bunnings NZ or Mitre 10, and they come in different styles, from simple tarp covers to fancy solar ones.

Install a Natural Filtration System

Instead of relying solely on chlorine, you can use natural filtration methods like bio-filters or plants that clean the water for you. Think of it like a pond or a freshwater stream—plants and beneficial bacteria do the work. A living pool setup (sometimes called a natural pool) uses a designated regeneration zone with aquatic plants to naturally filter out impurities. You can check out Biotop Natural Pools NZ for inspiration on how this works.

Use a Saltwater System

A saltwater pool is still technically using chlorine, but at much lower levels. It turns salt into chlorine naturally, which means no harsh chemical smell or burning eyes. Plus, it keeps algae and bacteria under control. Companies like Allied Pools & Spas or Pool & Spa Warehouse NZ can help you switch over if you’re thinking about it.

Add Baking Soda for Water Balance

You know how baking soda keeps your fridge fresh? It does something similar for your pool. Adding a bit can help stabilise the pH levels and prevent the water from getting too acidic or too alkaline. It’s also way cheaper than most pool-balancing products at your local New World or Pak’nSave.

Harness the Power of Oxygen

Instead of chlorine, you can sanitise your pool with an oxygen-based system. Oxygen sanitisation uses ozone or hydrogen peroxide to treat the water without leaving behind chemicals that irritate your skin and eyes. It’s a great way to get that fresh, clean water without the chemical kick. Check out EnviroSwim NZ for some great non-chlorine options.

Keep the Right Water Circulation

Stagnant water is a breeding ground for algae. Make sure your pool pump is running efficiently, keeping water moving and filtering out gunk. If you already have a pump but aren’t sure if it’s doing the job, places like Para Rubber NZ sell eco-friendly pump options that use less energy while keeping the water fresh.

Regularly Clean Your Pool—Naturally

Instead of using strong chemical-based cleaners, stick to scrubbing the sides and bottom with a pool brush and using a skimmer to grab any floating leaves or debris. You can even DIY a natural pool cleaner by mixing vinegar and water—it helps break down calcium buildup and keeps things looking good without harsh chemicals.

Consider Natural Enzyme Treatments

Enzymes naturally break down oils, sunscreen, and other organic gunk that ends up in your pool. Think of it like probiotics for your water. A little goes a long way, and it helps reduce chlorine demand. You can find natural enzyme treatments through Eco Pool Solutions NZ or Poolstore NZ.

The Bottom Line

You don’t have to rely on harsh chemicals to keep your pool clean. Simple tricks like using a pool cover, keeping your water moving, adding baking soda, or even switching to a saltwater system can make a big difference. Plus, with natural filtration and enzyme treatments, you can get that crystal-clear water without the chemical overload. Give these ideas a shot, and your pool will thank you.
