4.5" x 20" GAC/UDF + Phosphate Crystals (Scale Reduction) ro/di The kit will work asProduct Overview The LiquaGen 4. 5 x 20 GAC UDF + Phosphate Crystals Filter Cartridge is our largest dual stage Big Blue cartridge, combining Granular Activated Carbon (GAC UDF) with phosphate crystals for superior water treatment. The GAC UDF layer reduces chlorine, taste, odor, and organic contaminants, while the phosphate crystals prevent scale buildup and protect plumbing and appliances from corrosion. With its 4. 5 diameter and 20 length, this
