The Söchting Oxydator: A Silent, Power-Free Way to Boost Aquarium Oxygen and Health

 Let’s talk about something a bit different in the aquarium world—the Söchting Oxydator.

What exactly is it?

A Söchting Oxydator is a small device you place inside your aquarium that quietly increases oxygen levels in the water—without using electricity, air pumps, or even bubbles. And that’s what makes it so interesting. There’s no noise, no tubing, no visual clutter—just a simple, almost invisible way to improve your tank’s environment.

How does it actually work?

Inside the Oxydator, you add a diluted hydrogen peroxide solution. There’s also a ceramic catalyst in there. The catalyst slowly breaks down hydrogen peroxide into water and oxygen. That oxygen is then released directly into the aquarium—but not as bubbles. Instead, it dissolves directly into the water, making the process highly efficient and gentle.

What does that mean for your aquarium?

First, it increases dissolved oxygen levels, which are essential for fish, shrimp, and beneficial bacteria. Better oxygen levels mean healthier livestock—less stress, better breathing, and improved overall vitality. This becomes especially important in warmer water, where oxygen levels naturally drop.

It also helps improve water quality. By supporting beneficial bacteria, the Oxydator indirectly helps with the breakdown of waste products like ammonia and nitrite. That contributes to a more stable and balanced tank.

Another benefit people often notice is reduced algae issues. It’s not a miracle cure, but by improving overall water conditions and oxygen levels, it can make the environment less favourable for certain types of algae.

And then there’s the aesthetic side. Because it doesn’t rely on pumps or bubbles, it keeps your aquarium looking clean and natural. That’s a big plus if you’re going for a minimalist or aquascaped setup.

It’s also surprisingly useful in emergencies. If you ever have a power outage, the Oxydator keeps working, continuing to supply oxygen when your filters and pumps might be offline.

A couple of things to keep in mind.

You do need to use the correct concentration of hydrogen peroxide—too strong, and it could be harmful to your fish or shrimp. And like anything, it’s not completely hands-off. You’ll need to refill it from time to time.

Also, it’s important to understand that it’s not a replacement for proper filtration or regular water changes. Think of it as a supplement—something that enhances your tank rather than doing all the work on its own.

When is it most useful?

It’s especially popular in shrimp tanks, heavily stocked aquariums, warmer setups, or low-tech tanks with limited water movement. Basically, anywhere oxygen levels might be less than ideal.

If you compare it to a traditional air pump, the difference is pretty clear. Air pumps use electricity, create noise, and produce visible bubbles. The Oxydator, on the other hand, is silent, doesn’t need power, and delivers oxygen directly into the water in a much subtler way.

To sum up, the Söchting Oxydator is a simple, clever device that quietly boosts oxygen, supports water quality, and keeps your aquarium looking clean. It’s not essential for every tank, but in the right setup, it can make a noticeable difference.
