The JBL SilicatEX is a special filter material which eliminates silicic acid and phosphates, key causes of algae. Silicates especially are found in mains water, so using a good media to remove it makes life easier for you and keeps a clear fish tank.

It works best if placed within an external fish tank filter or sump, this means that it can treat all of the water as it passes through. The media will absorb silicates and phosphate from the water, preventing the formation of algae.

This is how to have a beautiful aquarium without troublesome algae:

Diatoms form brownish coatings on plants, aquarium base and decorations. They occur when your water contains more than 0.4 mg/l silicic acid/silicates (SiO2). The silicic acid mainly comes from your tap water. It serves to develop the skeletal structure of the diatoms. To combat the algae, just remove the silicic acid from the water and they will die or have no opportunity to form. Diatoms are neither toxic nor harmful. They even form a part of the nutritional basis for 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.

Distinguishing between diatoms and slimy algae:
Both algal groups can look very similar. But when you take them between your fingers you can feel the difference: slimy algae feel greasy-slimy even after rubbing them longer, whereas diatoms feel rough.

Special filtering:
SilikatEx 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.

  • Filter material for the removal of silicic acid (silicate) in fresh and marine water to prevent diatoms.
  • Rinse, fill in filter bag (enclosed) and place in filter. Rinse after one to two weeks.
  • Diatoms can form brown unsightly deposits on gravel, decoration material and plants.
  • Silicate content can be checked with silicate test. Result: values below 0.4 mg/l silicate prevent diatoms.
  • Guaranteed efficiency: binds up to 30,000 mg silicate (SiO2)/ kg. Including net bag and sealing clip.
