Sera Siporax Pond Protect Professional
Abrasion-proof high-performance filter medium designed for all pond filter setups.
The Sera Siporax Pond Protect Professional is a biological filter medium featuring a protective ball that prevents abrasion. It was specifically developed for use in filter systems with strong water agitation. The outer cover shields the internal Siporax ring and directs water flow directly into it, ensuring even water distribution through the sintered glass ring. This enhances oxygen intake, improving the nitrification performance of filter bacteria.
Thanks to its unique three-dimensional tunnel structure with abundant pores, the internal Siporax provides ideal settling conditions for filter bacteria, maximizing surface area for biological activity.

Installed the Siporax Pond Protect in my pond filter after a few months of using the standard medium. The water clarity improved noticeably within a week. The filter runs smoothly even during heavy rain when water flow is strong. No signs of wear after two months of use. Highly recommend for active pond systems.

After switching from the regular Siporax, I noticed better biological activity in the filter. The water flow is more consistent, and the filter handles turbulence well. The protective ball keeps the internal ring intact, which is a big plus for high-activity ponds.

Works well in my koi pond with strong water movement. The filter seems to maintain better bacterial balance. A bit more expensive than basic filters, but the performance improvement justifies the cost.
