Ziss ZM-2 Moving Filter Media
The Ziss ZM-2 Moving Filter Media is a premium floating biological filtration media designed specifically for moving bed filtration systems. Manufactured from durable, high-surface-area plastic, ZM-2 provides an ideal environment for beneficial bacteria to colonise, helping rapidly break down harmful ammonia and nitrite while maintaining exceptional water quality.
Designed to remain in constant motion inside a moving bed filter, the media continually tumbles as air is introduced into the filter. This constant movement naturally cleans the media’s surface, preventing clogging and ensuring beneficial bacteria always receive maximum oxygen and water flow. The result is highly efficient biological filtration with minimal maintenance.
Perfect for use in Ziss Silent Bubble Moving Filters.

I’ve used the ZM-2 media in my Ziss Silent Bubble filter for three months now. The water clarity has improved significantly, and I notice less ammonia spikes. The media stays clean and doesn’t clog easily, which saves me time on maintenance.

The media works well with my existing filter setup. It’s easy to install and the constant movement keeps the surface active. I see better nitrite control compared to my previous filter media.

After switching to ZM-2, my tank has stabilized faster. The bacteria colonization is strong, and the water quality remains stable even during heavy fish feeding.
