The Dupla Duresin SI silicate resin is a regenerable silicate resin for the complete demineralisation of tap water and suitable for use with osmosis systems. It binds residual silicates in the permeate (pure water of the reverse osmosis system). 1,000 ml can bind up to 10,000 mg of silicate. Above all, high levels of silica in tap water are often a problem in aquaristics despite the use of reverse osmosis water. With a silica concentration of 5 mg in tap water and a retention rate of 95% in a reverse osmosis system, a residual silica concentration of 0.25 mg is still retained in the permeate. This concentration alone can lead to a diatom problem. Duresin SI is suitable for use with empty filter housings!
Our expert Oliver Knott recommends:
With Dupla Duresin SI you completely remove residues from your osmosis water!
