Unleash the Power of Nature

Crystal clear water. Without the hard work

Nualgi’s patented water treatment + super-strength bacteria in PondPatrol work together to recalibrate your pond chemistry. With a small regular dose of both, you give nature the helping hand she needs to rebalance your pond’s ecosystem. The result? A beautiful crystal clear pond that is a haven to fish and wildlife – and a joy to sit beside.

Is it snake oil?
No, it’s simple pond chemistry

So what’s going on in your pond when you give it a dose of Nualgi + PondPatrol?

It’s all about the hard work of a few microscopic heroes.

Diatoms are tiny algae that are essential for a healthy pond. Nualgi is food for these diatoms, so they experience a growth boost, consuming more of the nitrogen and phosphorus in the water. Because diatoms photosynthesize faster and in less light, they outcompete the bad algae and starve it of food – preventing it from turning your pond green.

PondPatrol is a concentration of good bacteria that help to clean your pond. Instead of a build up of ugly and smelly organic waste – like fish poop, excess food, and dead plants – these little wonderkids eat it. They also reduce ammonia, nitrate and phosphate levels, which helps our diatom friends thrive. And to return the favor, the diatoms produce oxygen which helps the good bacteria thrive. So the two work together in a virtuous pond cleaning cycle.

After my first dose of Nualgi, I returned to the pond a week later and for the first time in two years not a single strand of hair algae had returned.

HOW DOES IT WORK?

Within 3 – 5 hours of applying Nualgi Ponds, a bloom of Diatom algae (the good kind!) will develop. The diatom algae bloom out-competes nuisance algae for CO2, N, P and other nutrients, causing the bad algae to die off. It then locks away some of the harmful nutrients in the new bio mass that is consumed as live food for your fish and zooplankton.

Safe for Fish, Plants & All Types of Ponds

Nualgi Ponds can be used in any outdoor water feature to naturally control algae, improve water quality & reduce foul odors.
