Treat algae naturally & safely

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.
