Description

X-Pores – 20–30 mm (Large-Grade Natural Volcanic Filter Media Rocks)

#pumice stone

X-Pores Large-Grade Filter Media is made from natural volcanic rock selected for superior biological filtration and long-term durability. These big-size porous stones provide extremely high surface area, allowing beneficial nitrifying bacteria to colonize deeply inside the rock structure. This ensures powerful and stable ammonia and nitrite breakdown even in high bioload aquarium and pond systems.

The larger dimensions (20–30 mm) make this media ideal for sumps, trickle towers, overflow chambers, pond filters, and large biological reactors where maximum oxygen exchange and long-term bacterial colonization are required.
