This is Catalyst replacement for Sochting Oxydator. Please choose options for your Oxydator.

Using a patented method, Söchting Oxydator produces normal and activated oxygen in the aquarium by means of Oxydator solution and special ceramic catalysts. The activated oxygen decomposes particularly putrid matters and toxicants and, thus essentially improves the well-being of fish and plants. Pure oxygen created by the Söchting Oxydator is mostly immediately dissolved in the water, so that there are hardly any bubbles produced.

Due to the Oxydator's oxidizing capacity, the water quality will be improved and harmful contaminants in the water will be neutralised and In the summer, it is effective at fighting algae. The benefits of adding hydrogen peroxide to an aquarium in cases of acute oxygen deficiency, water putrefaction and water turbidity, have been known for a long time.


The filling level of the Oxydator can be monitored through the transparent plastic cylinder.
The amount of oxygen that is given off depends on the water temperature. The higher the temperature, the more oxygen is produced, the lower the temperature, the smaller the amount of oxygen. Thanks to this phenomenon, your aquarium is always provided with the ideal amount of oxygen. The operating time of the Oxydator shortens or extends accordingly.

For oxydator solution:

The best and cheapest way is to make your own solution using the 35% Hydrogen Peroxide Food Grade. You must "dilute" with pure distilled/RO water to achieve the desired concentration as follows:

1 part 35% Hydrogen Peroxide to 6 parts distilled water yields the recommended 6% solution for the Oxydator
For example: 10ml of 35% Hydrogen Peroxide plus 60ml of distilled water = 70ml cups of 6% Hydrogen Peroxide.
A 1-to-2 ratio of 35% Hydrogen Peroxide to distilled water would yield an 18% Hydrogen Peroxide solution.
A 1-to-3 ratio of 35% Hydrogen Peroxide to distilled water would yield a 12% Hydrogen Peroxide solution.
Thus you can adjust the % Hydrogen Peroxide as desired to accommodate the rate at which oxygen is dispensed into the aquarium.

You can buy this on ebay by a quick search "Hydrogen Peroxide Food Grade 35%".
