Why Remove Pool Algae Naturally?
Algae in your pool isn’t just an eyesore; it can make surfaces slippery and increase maintenance costs if left unchecked. While many pool owners turn to chemicals like chlorine and algaecides, there are natural alternatives that can effectively remove algae without harsh chemicals. Whether you’re looking for an eco-friendly option or simply want to reduce chemical use, here’s how you can clear up your pool the natural way.
1. Brush and Skim Your Pool Regularly
One of the simplest ways to prevent and remove algae is by manually scrubbing the pool walls and floor. Algae cling to surfaces and can be tough to remove once established.
- Use a pool brush with stiff bristles to scrub surfaces, especially in problem areas such as steps, corners, and shaded spots.
- A skimmer or pool net can help remove floating algae before it settles.
You can find suitable pool brushes and skimmers at local retailers such as Mitre 10 or Bunnings NZ.
2. Increase Filtration and Circulation
Poor water circulation creates stagnant areas where algae thrive. Ensuring your pool filter is running efficiently can prevent algae buildup and help clear existing blooms.
- Run your pool pump longer – aim for at least 8-12 hours per day during hot weather.
- Clean your pool filter regularly to remove trapped debris and algae spores.
- Direct return jets to push water into hard-to-reach areas where algae may form.
If your pool pump or filter system needs maintenance, businesses like Pool and Spa Warehouse NZ offer parts and servicing.
3. Use a Pool Vacuum to Remove Algae
Algae often settle at the bottom of the pool, forming slimy patches. A manual or automatic pool vacuum can help physically remove it.
- A manual pool vacuum lets you focus on problem areas.
- Robotic pool cleaners can run automatically, making the process easier.

4. Maintain Proper Water Balance
Even without chemicals like chlorine, it’s essential to keep the pH and alkalinity levels balanced to prevent algae from thriving.
- Aim for a pH level of 7.2 to 7.8.
- Alkalinity should be between 80-120 ppm.
- Test your water weekly using a pool testing kit from retailers like Swimming Pool Supplies NZ.
If pH is out of balance, natural alternatives such as baking soda (for alkalinity) and vinegar (to lower pH) can help.
5. Use Natural Algae Removers
Several natural methods can effectively tackle and prevent algae growth:
- Saltwater Pools: If you have a saltwater chlorinator, the natural chlorine it produces helps keep algae at bay.
- UV Pool Sanitisers: UV light systems, available from The Pool Shop NZ, destroy algae spores without chemicals.
- Hydrogen Peroxide: A food-grade hydrogen peroxide solution can act as a natural oxidiser against algae.
- Barley Straw or Barley Extract: Available at garden centres, barley releases compounds that inhibit algae growth.
6. Use a Pool Cover When Not in Use
Sunlight fuels algae growth, so covering your pool when it’s not in use can prevent outbreaks. Consider investing in:
- A solar cover, which also keeps the pool warm.
- A mesh safety cover, which prevents debris from entering while allowing rainwater to drain.
New Zealand pool retailers like Cover Systems NZ supply a range of pool covers.
7. Shock With High-Temperature Water
If your pool has a heated system, temporarily raising the water temperature can help kill off algae naturally. Running the heater above 30°C for a few hours may help eliminate spores.
Final Thoughts
Maintaining a clean, algae-free pool without chemicals requires a combination of physical cleaning, filtration, water balance, and natural treatments. By following these steps and using products available from local NZ stores, you can enjoy a cleaner and healthier swimming experience all summer long.
