When you need high purity water for your laboratory, manufacturing, or reefkeeping / aquarium water, a deionization system is an excellent option. Deionized water systems (or water deionizers) remove nearly all ions from your water, including minerals like iron, sodium, sulfate, and copper. Since these ions make up most non-particulate water contaminants, you'll get high purity water quickly and affordably.
Years ago, high purity water was used only in limited applications. Today, deionized (Dl) and high purity water has become an essential ingredient in hundreds of applications. Just a few include the following:
Large aquariums, fish tanks, and reefkeeping facilities
Electronics manufacturing plants
