Sera Siporax Professional 5.1oz
The Sera Siporax Professional 5.1oz is an exceptional choice for enhancing biological filtration in freshwater, marine aquariums, and ponds. It significantly boosts the surface area essential for biological cleaning, providing an ideal environment for beneficial filter bacteria to thrive.
In natural water bodies, decomposition at the bottom is crucial. Micro-organisms break down organic waste, converting it into nutrients for aquatic plants and eliminating harmful substances such as ammonium, nitrite, and nitrate. While nature provides ample surface area for these processes, the confined space of an aquarium requires expanded surface area to ensure thorough waste breakdown.

I’ve used this in my 55-gallon freshwater tank for three months. The water clarity has improved noticeably, and I see less algae growth. The bacteria colonization is steady, and the filter runs smoothly without clogging.
Jennifer Randall –
Works well with my external filter. I noticed a reduction in nitrite levels after two weeks. It’s easy to add and doesn’t require any special setup. Good value for the surface area it provides.
Wendy Murray –
Installed it in my marine tank along with a trickle filter. The water parameters have stabilized, and the biological activity seems more consistent. No issues with performance or compatibility.
