Overview

Aqua Medic Sulfur Pearls are formed from pure sulphur. They are used in Sulphur nitrate reactors as the filter medium and energy source for the bacteria. They have to be replaced from time to time as they are slowly consumed by the bacteria. Caution: Use only in nitrate removing anaerobic filters having a low water flow rate. The pH value and carbonate hardness (alkalinity) of the aquarium must be monitored regularly. We recommend sulphur filters are only used only in combination with a hardness reactor, filled with ab Hydrocarbonate, to neutralise the acid produced.

Sulphur beads for refilling the ab Aqua Medic Silphur reactor or the Sulphur nitrate reductor. Available in 1000 ml and 5000 ml box size.

Reviews from our customers:
Kushan F. wrote about Aqua Medic Sulfur Pearls in 2025:
I bought the Aqua Medic Sulfur Pearls for my marine sulfur denitrator and they work well. The pellets are uniform with minimal dust, and a quick rinse was enough. With very low flow and a 12 week break-in, nitrate reduction was steady and stable. There was a faint sulfur smell at the start, which disappeared once the reactor settled. Youll need periodic top-ups, but the performance and price make this an easy re-buy.
