The catalyst is the heart of Söchting technology: it converts the hydrogen peroxide solution into pure active oxygen in a controlled manner. Over time, it loses reactivity, resulting in reduced oxygen production. A fresh catalyst will immediately restore your Oxydator Mini to full capacity. The set contains 2 pieces, so you always have a spare on hand.

When and why to replace?

• Decreased Performance: Is your Oxydator producing bubbles less frequently, even though there's still solution? This is the classic sign of an exhausted catalyst.
• Increased Solution Consumption: Paradoxically, an aging catalyst can decompose the solution uncontrollably faster – in this case, a replacement is also due.
• Original Quality: Only original Söchting catalysts guarantee the reaction rate and lifespan specified by the manufacturer.
• Pack of 2 – Practical: One catalyst remains as a spare, so you don't have to order one when you need it.

Practical Tip:

Note the date you installed your catalyst. Depending on the solution concentration and aquarium size, a catalyst can last several months. Checking its condition every 3–6 months and replacing it if necessary will ensure a continuously optimal oxygen supply – particularly critical during the warm season when O₂ levels in the water naturally drop.
