Aquatech Dephos is a high-performing adsorption granulate based on iron hydroxide. It was specifically developed for adsorptive removal of phosphate and  silicate from water in fresh and seawater aquariums and garden ponds.

Due to its large surface area of over 250m²/g, it can bind phosphate ions quickly, effectively and binds them irreversibly to the filter medium.

All of the production facilities are audited yearly to international standards and the special production and drying procedure of Aquatech Dephos makes it a very robust, stable, long lasting media and highly reactive to phosphates.

The advantage of Aquatech Dephos over other media is its large adsorption surface. This makes the Aquatech Dephos media many times more effective because of the nanosized porous internal structure and surface.

Aquatech Dephos is available in two different grain sizes and can therefore be used both in special filter cartridges which operate on the suspension bed filter principle and filter bags that can be inserted in any multi-layer filter.
