CupriSorb is an exceptional adsorbent specifically designed to capture copper and heavy metals. It outperforms carbon in the swift and efficient removal of copper, making it an excellent choice for urgent copper elimination. CupriSorb effectively extracts all forms of copper, including chelated varieties, maintaining its potency until it changes to a deep blue-black hue. It can be regenerated multiple times. When used continuously, it will gradually remove even precipitated copper from the gravel or substrate bed. CupriSorb enables the care of invertebrates in tanks that have been treated with copper by eliminating the copper leaching from substrates. CupriSorb is a robust chelating resin that specifically targets copper. Unlike competing options, which are simply cation exchange resins, CupriSorb is effective in both freshwater and saltwater environments, while others may only work in freshwater. FEATURES: Highly effective adsorbent for copper and heavy metals Copper-specific chelating resin Removes all forms of copper DIRECTIONS: For every 600 L (150 US gallons), use 250 mL to eliminate up to 7,500 mg (12 ppm) of copper. Place it in a filter media bag, such as The Bag. To achieve optimal results, position CupriSorb to enhance water flow through it. To effectively address undetectable copper leaching from substrates, keep CupriSorb in use for a minimum of 2 weeks after copper tests indicate no copper presence. It can be utilized in a canister filter, chemical filtration module, box filter, or any area with high flow in a trickle filter.Expires on 19 May 2030
