US Water offers the highest quality high-purity deionization or DI resin, semiconductor grade DI resin and color-changing DI resin. In our experience, the highest capacity and best resin is the Resintech Semiconductor Resin. People with aquariums and reefkeeping systems like the color-changing DI resin, but remember, it does not have the same capacity as the semiconductor-grade resin. That means that you won't get as many gallons out of the color-changing resin as you will from the semiconductor grade resin.
