1Kg Elemental Sulphur



1Kg Sulphur Pastille to suit all Sulphur denitrification reactor's.

Australian made Sulphur Pastille's formed from pure sulphur. These are used in Sulphur nitrate reactors as the filter medium and energy source for the bacteria. The pastille's have to be topped up 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 alkalinity of the aquarium must be monitored regularly. We recommend sulphur filters are only used only in combination with a hardness reactor filled with Hydrocarbonate to help raise pH & alkalinity.
