Chemi-Pure Blue is a high-performance blend of premium activated carbons and synthetic ion exchange resins designed for superior water purification in saltwater and reef aquariums. This advanced filter media effectively removes a wide array of undesirable elements, including organic compounds, odors, phenols, toxins, medications, dissolved metals, phosphates, and silicates from your aquarium water, ensuring a pristine environment for your aquatic life. This sophisticated filter media actively enhances ORP/redox potential and stabilizes pH, leading to a visibly healthier aquarium with unparalleled water clarity. It safely removes copper and other toxic heavy metals without harming beneficial biological organisms, and also helps to reduce the frequency of water changes. While one 5.5 oz jar effectively treats 35 gallons, this larger 44oz container is ideal for sustained use or larger systems. Chemi-Pure Blue is an essential product for saltwater and reef aquarium enthusiasts looking to maintain optimal water quality and promote the well-being of their fish, corals, and invertebrates. It aids in faster acclimation and thriving environments for sensitive corals and invertebrates, making it suitable for both beginner and experienced hobbyists striving for a vibrant and stable marine ecosystem. It is also suitable for freshwater African Cichlid aquariums but not recommended for standard freshwater setups.
