Boost your pond’s biological capacity with Oase Hel-X 13 Biomedia 25L. Engineered for moving bed filter systems like the Oase ProfiClear range, Hel-X 13 provides an impressive 806 m²/m³ of protected surface area for bacterial colonization. Its specialized helical wheel design stays in constant fluid motion, breaking down harmful ammonia and nitrite while self-cleaning to maintain peak biological efficiency.
Product Description
Biological filtration is the foundation of a healthy koi pond, and Oase Hel-X 13 Biomedia 25L delivers maximum biological processing power in a compact footprint. Developed specifically for Oase ProfiClear drum and moving bed filter systems, this advanced bio-media provides an ideal environment for beneficial nitrifying bacteria (Nitrosomonas and Nitrobacter) to convert toxic ammonia and nitrite into harmless nitrate.
Key Features & Performance Metrics
- Massive Protected Surface Area: Features 806 m² of protected surface area per m³ (with a total surface area of 955 m²/m³). The protected inner structure shields delicate bacterial colonies from mechanical collisions as the media tumbles.
- 13% Increased Settlement Area: Compared to original Hel-X 8 media, Hel-X 13 offers a 13% larger surface area, allowing higher stocking densities and increased daily feeding rates without expanding your filter volume.
- Self-Cleaning Fluidized Action: Aeration in moving bed chambers keeps the media tumbling continuously. This constant movement prevents dead spots, ensures oxygenation, and sloughs off old bio-film to make room for active growth.
- Reduces Food Breakdowns: Efficiently handles organic waste loads, maintaining crystal-clear, fish-safe water quality year-round.

Maturation & Setup Tips
- Initial Buoyancy: Brand-new Hel-X 13 media floats initially due to trapped air and clean surfaces.
- Maturation Time: Within 2 to 4 weeks, a mature biological film coats the media, making it neutral in buoyancy and allowing it to tumble freely in aerated water.
- Kickstart Colonization: To accelerate the maturation process and avoid unwanted ammonia spikes, seed your filter chamber with high-quality filter bacteria (such as Evolution Aqua Pure Pond or Filter Gel) during installation.
