The water you add to your aquarium has a tremendous influence on the long-term success of your aquarium. While tap way may meet drinking water standards, in most cases it is unacceptable for aquarium use. Your water supply is likely treated with phosphate-based anti-corrosion chemicals and chlorine disinfectants. Nitrates, heavy metals and other contaminants can make reef-keeping difficult. Fortunately, a reverse osmosis (RO) filtration system will make your tap water reef-safe. The IceCap RO/DI system is purpose-built for making the purest water for your aquarium. The four-stage filtration system starts by capturing tiny particles of iron oxide (rust), sand and other grit that can clog the RO. Next, the water passes through an activated carbon cartridge that removes chlorine disinfectants and organic chemicals. The water then passes through the RO membrane where nitrates, phosphates and heavy metals are removed from the water. The last stage uses deionization to remove any trace pollutants, like silicates, from the water. The ultra-pure RO/DI water is perfect for mixing saltwater, toping off and making water changes. We also carry all the maintenance parts and replacement filters to keep your purification system running smoothly.
