RO/DI Systems

We carry a large variety of RO and RO/DI systems that remove impurities—chlorine, chloramines, pesticides, phosphates, heavy metals and many others—from tap water. DI (De-Ionizing) cartridges do an excellent job of removing phosphates, silicates and nitrates from tap water. They are highly recommended for reef tanks.
