Everything You Need to Know About Ozone for Koi Ponds
Expert Insights from Columbia Water Gardens
In the world of high-end koi keeping, the difference between a "good" pond and a "world-class" pond often comes down to one molecule: Ozone (o3). While bio-filtration handles the nitrogen cycle, ozone handles the microscopic pollution that traditional filters simply cannot touch.
What is Ozone (o3)?
Ozone is an "unstable" form of oxygen. While the air we breathe is o2, ozone contains a third oxygen atom looking for a reason to break off. When that atom hits a piece of organic waste, a bacteria cell, or a virus, it oxidizes it—effectively "burning" it at a molecular level without heat.
The Top Benefits of Ozone Systems
- Unmatched Clarity: Ozone destroys the dissolved organic compounds (DOCs) that create a yellow or tea-colored tint in the water.
- Pathogen Control: It kills harmful bacteria like Aeromonas and Pseudomonas on contact, reducing fish ulcers and infections.
- Higher Oxygen Levels: After the oxidation process, ozone reverts back into pure, life-giving oxygen (o2).
- Better Skimmer Performance: Ozone acts as a micro-flocculant, clumping tiny particles together so your mechanical filters can actually catch them.
Installation & Pricing Ranges
Pricing includes professional installation, the ozone generator, an air dryer/oxygen concentrator, a venturi injector, a digital ORP controller for safety, and 24/7 wifi monitoring with reports for the first year. After that, we charge a nominal fee for continued monitoring.

Ozone FAQ: Answers for Pond Lovers
Click a question below to learn more about how ozone interacts with your aquatic environment.
Ozone is a powerful oxidizer and can be harmful if it enters the pond directly. However, we install ORP Controllers that monitor the water 24/7. If the "redox" level gets too high, the system automatically shuts off. We also use a "de-gas" chamber to ensure only oxygen-rich water returns to the fish.
Yes. Ozone is highly effective at killing single-cell algae (green water). While it won't magically disappear string algae growing on rocks, it removes the excess nutrients that allow string algae to thrive.
No. The beneficial bacteria in your biological filter live in a "biofilm" on your media. Ozone is injected into the plumbing line and reacts quickly. By the time the water hits your bio-filter, the ozone has turned back into oxygen, which actually helps your good bacteria work faster!
You will see two things: First, the ORP controller will give you a digital reading of your water's purity. Second, you will notice a visible difference in water clarity within 48 to 72 hours—your water will look like liquid glass.
ORP stands for Oxidation-Reduction Potential. It is a measure of the "cleanliness" of the water. A typical pond sits around 150-200mV. An ozone-treated pond usually stays between 300-350mV. The controller ensures it never exceeds the safe limit for fish.
Ozone is pH neutral. Unlike some chemical treatments, it will not cause your pH to swing or crash, making it one of the safest ways to maintain high-quality water for sensitive koi breeds.
