Dupla Phosphate & Silicate Filter







  • Description
  • Specifications

The Dupla Siliphos filter reliably removes phosphates and silicates in freshwater and marine aquariums. The Siliphos filter is filled with 500ml of Dupla Siliphos and can be operated with a separate pump or can be connected to nearly every common aquarium filter type.


Dupla Siliphos ensures that phosphates and silicate levels are kept as low as possible and water values in the aquarium are optimised. Siliphos is suitable for use with fresh water and sea water and has been used successfully for years in the industry.Even when the load is depleted, none of the chemical load is returned to the water.


The filter casing must be mounted vertically. The flow direction is from bottom to top, in order to press the air out of the filter container. This ensures that the entire filter material is coated with water.
