There are two distinct uses for deionizing resins. One is to treat water for a water change and one is to directly treat the aquarium water to remove nitrates or ammonia. Neither use is a very good use of monetary resources, to put it mildly.<\/p>\n\n\n\n

What is DI (Deionizing or Ion Exchange) resin?<\/h5>\n\n\n\n

From Wikipedia:<\/p>\n\n\n\n

\u201cAn ion-exchange resin or ion-exchange polymer is a resin or polymer that acts as a medium for ion exchange. It is an insoluble matrix (or support structure) normally in the form of small (0.25\u20130.5 mm radius) microbeads, usually white or yellowish, fabricated from an organic polymer substrate. The beads are typically porous, providing a large surface area on and inside them. The trapping of ions occurs along with the accompanying release of other ions, and thus the process is called ion exchange.<\/em><\/p>\n\n\n\n

There are multiple types of ion-exchange resin. Most commercial resins are made of polystyrene sulfonate. Polystyrene sulfonates are polymers derived from polystyrene by the addition of sulfonate functional groups. They are widely used as ion-exchange resins to remove ions such as potassium, calcium, and sodium from solutions in technical or medical applications.\u201d<\/em><\/p>\n<\/blockquote>\n\n\n\n

This is a very accurate description of DI resins.<\/p>\n\n\n\n
