Keeping your pool water clear without dumping in a bunch of chemicals? Totally possible. Here’s how you can do it naturally while still enjoying crystal-clear water.
Keep the Water Moving
Stagnant water is a breeding ground for algae and bacteria. If your pool pump isn’t running enough, that’s probably why the water’s looking a bit off. In New Zealand’s warm summer months, running your pump for at least 6–8 hours a day is the way to go. Even better—get a solar-powered pool pump from Sunergy Solar to keep it running efficiently without adding to your power bill.
Skim Daily and Vacuum Weekly
Think of your skimmer like your pool’s first line of defence—it grabs leaves, bugs, and other floating debris before they sink and start decaying. A quick skim with a net once a day is all it takes. And don’t forget to vacuum once a week; this helps get rid of dirt and sludge before they turn into bigger problems. You can grab a robotic pool cleaner from Bunnings NZ if you want to make your life even easier.
Use a Pool Cover
This one’s a game-changer. It keeps leaves, dirt, and rainwater (which can mess with your pool’s balance) out of the water. Plus, it helps keep the water warm overnight. Looking for a cover? Check out Para Rubber for options that fit most pool sizes.
Keep pH and Alkalinity in Check
Even if you’re avoiding chemicals, keeping pH balanced is a must. If your pool is too acidic or too alkaline, bacteria and algae will love it. Aim for a pH between 7.2 and 7.6 and an alkalinity level between 80-120 ppm. Baking soda (yes, the same stuff you use in the kitchen) can help stabilise alkalinity, and you can usually find it in bulk at Countdown or Pak’nSave.
Try Natural Pool Cleaners
Instead of chlorine-heavy pool chemicals, try natural alternatives:
- Saltwater chlorinators – Convert salt into a natural form of chlorine, which is gentler on your skin. Brands like Davey Water offer excellent chlorinators built for NZ conditions.
- Hydrogen peroxide – A powerful oxidiser that kills bacteria without the strong chlorine smell. You can find pool-grade hydrogen peroxide at Mitre 10.
- Enzyme cleaners – These break down oils and organic gunk naturally. Look for them at Pool & Spa Warehouse.
Use Plants for Natural Filtration
If you’re really into going chemical-free, you could try a natural pool system that uses plants to filter the water. It’s a big project, but companies like Landscapes by Lush specialise in transforming pools into eco-friendly swimming spots that don’t need chlorine or salt.
Sprinkle in Some Good Bacteria
Adding beneficial bacteria (like you’d find in pond treatments) can help break down algae and organic matter naturally. You’ll find natural bacterial pool treatments at Aquatic Lifestyles NZ.
Shock with the Sun
Instead of using chemical shock treatments, let the sun help! On a bright sunny day, aerating your pool by turning on water features or stirring up the water with a pool brush can boost oxygen levels. This helps break down unwanted contaminants naturally.
Rinse Off Before You Swim
Sunscreen, deodorant, sweat, and hair products all contribute to murky water. A quick rinse before hopping in can keep the water cleaner for longer. Consider setting up an outdoor shower—**Mitre 10** has great DIY kits for this.
The Bottom Line
Keeping your pool water naturally clear isn’t about skipping maintenance—it’s just about being smart with how you do it. Keep the water moving, maintain your pH, use natural cleaners, and don’t let debris stick around too long. Try a few of these tricks and see what works best for your pool.
