SilicatEx removes silicate from fresh and marine water aquariums. It removes from the main nutrients the unwanted diatom algae (brown coatings), which often appear after freshwater has been added. SilikatEx Rapid also removes phosphate etc. and thus curbs the growth of other algae. The filter material creates biotope-like living conditions.

Diatoms (often called Brown Algae) form a brown coating on plants, substrate and decor. Brown Algae is formed primarily when when your water contains more than 0.4 mg/l silicic acid/silicates (SiO2). The silicic acid is often found naturally in tap water. Diatoms (brown algae) use silicate to form their skeletal structure. So in order to combat the algae, just remove the silicic acid from the water and they will be unable to grow or form.

Diatoms are neither toxic nor harmful. They even form a part of the natural diet of grazing cichlids in Lake Malawi and Lake Tanganyika. But as algae form brownish coatings which are regarded as unattractive we tend to remove them from our aquariums. Often confused with slime algae, both algal groups can look very similar. But when you rub them between your fingers you can feel the difference: slimy algae feel greasy-slimy, whereas diatoms feel rough.
