Carbon filtration is an inexpensive and effective way to remove chemicals and contaminants commonly found in tap water. Aries Scale Inhibitor Carbon Block sequesters hardness, inhibits precipitation and deposit formation. Corrosion Inhibition forms a protective coating and provides corrosion protection from chloride, sulfate and silica. Each block is wrapped with a polypropylene outer layer and netting to prevent premature clogging of the carbon block.
