Indicator-Resin is a mixed bed resin to eliminate silicate, nitrate and other ions of osmosis water. The special silicate resin contributes to limiting the growth of diatoms, in particular for aquarophilia.
The resin is equipped with a color indicator that displays the efficiency of the filtering material. When the conductivity of desalked osmosis water starts to increase, the resin goes from blue to green and must be renewed.
