Note: Silicate Ex also binds phosphate. Therefore ï¬rst remove phosphate with Colombo Phosphate Ex to increase the effectiveness of Silicate Ex. Also, do not add phosphate to the water when Silicate Ex is in use.
Too high a silicate or silicic acid content is the main reason for the presence of silica algae (brown algae). By removing the silicate with Silicate Ex, the algae can no longer grow and disappear. Normally a maximum silicate content of 0.50 mg/l is acceptable, but to remove silica algae, the content must be temporarily reduced to 0.
