Quality Marine Water

Quality Marine Water

Good quality water conditions are essential for a thriving marine aquarium, whether its fish only or a mixed reef system.

Efficient filtration is a must, and the filtration media is an important factor. Seachem produce many different types of filtration media, which may be of benefit to your aquarium.


Matrix is a highly porous media designed to provide exceptionally efficient bio filtration for single site removal of ammonia, nitrite and nitrate from freshwater or marine aquaria. Each litre of Matrix provides over 160000cm2 of surface, equivalent to over 40 litres of typical “plastic ball media”.


de*nitrate removes nitrates, nitrites, ammonia and organics from both freshwater and marine water. The high porosity of  de*nitrate supports the proliferation of both aerobic and anaerobic bacteria that further remove these toxic aquarium byproducts. Even when exhausted as an organic adsorbent, de*nitrate continues to be an excellent support for the biological filter and does not have to be removed.


Seagel is a blend of MatrixCarbon and Phosguard. MatrixCarbon is an ultracapacity carbon for the removal of organic and colour impurities. Phosguard is a powerful remover of phosphate, silicate, toxic metals and acids.Both components are bead shaped for optimum water flow characteristics and penetration. The components enhance each other and are ideal for reef and marine use.
