Don’t risk your beloved fish with the use of algaecides. There’s a NATURAL way to balance your pond that’s SAFE. Unleash the power of nature with Nualgi Natural Pond Cleaner – crystal clear water without harmful algaecides.

Sizes: 60ml, 125ml, 250ml, 500ml


We're 100% Natural

Use Nualgi Natural Pond Cleaner to treat pond algae naturally and safely improve your pond environment.

Instead of killing algae, Nualgi Natural Pond Cleaner promotes the growth of diatoms – the good microbes that outcompete the bad algae and starve them of food – preventing them from turning your pond green. The result is crystal clear water, NATURALLY!

The growth of diatoms leads to more oxygen in the water which provides a healthier habitat for fish. With more oxygen in the water, fish become healthy, vibrant, less disease-prone and more active.

Enjoy peace of mind knowing that Nualgi Natural Pond Cleaner is 100% safe for all your pond’s inhabitants.

Natural Pond Care is Better

Man-made chemicals & UV sterilizers create a dependency that actually weakens your pond biology & prevents natural water chemistry from balancing.

Consistent use of Nualgi Natural Pond Cleaner can decrease or eliminate the use of harmful pond chemicals. This process typically takes 4 weekly treatments, but some pond owners will notice a significant improvement in water quality and clarity after their first dose.

Please be patient. Naturally balancing your pond’s water chemistry can take time but the benefits are worth it! If you’re in doubt or have questions, click here to speak with our experts.

Struggling with String Algae?

String algae is a filamentous species that attaches to plants, hangs from rocks in waterfalls, or hangs on the surface of the water (which is referred to as Blanket Algae). The long strands tangle together and form thick mats that can double their weight within 24 hours!


Get Rid of String Algae for Good!

Combine the power of diatoms with Nualgi Beneficial Bacteria and you get 6 specially chosen bacteria strains that eat organic matter and naturally clean your pond. This team of beneficial bacteria reduces ammonia, nitrate and phosphate levels and breaks down fish waste, toxins and odors.
