The Hydro Life Hydroponics Twin Filtration System removes chlorine, chloramines, salts, heavy metals, sulfur, sediment, rust flakes and other contaminants from your water. The pre-filter cartridge is a sacrificial filter that removes heavy sediment from water, helping to extend the life of the KDF 85/Catalytic Carbon filter cartridge. The KDF 85 filter cartridge has Catalytic Carbon filtration to provide you with safer, cleaner water and reduced chloramines from a potable water source. The KDF 85 media also reduces heavy metals such as lead and mercury. KDF 85 media bonds with chloramines and traps them within the KDF media. KDF 85 will also help prevent bacteria growth when the filter is not in use and to extend the overall life of your hydroponic filter. Durable cartridge filter has a wide body for high flow and a 8,000 gallon capacity with a 2.5 GPM flow rate. When first attaching the filter system to your water source, allow the water to run free for a few minutes to flush the initial loose carbon fines or dust out of the filter. When the water runs clear, the filter is ready for use.
