Has anyone used Seachem Laboratories CurpiSorb? The product description states that it will remove copper. I would like to keep shrimp but my first little guys did not fare well. Copper seems to be a huge concern. Advice?
SeaChem CupriSorb is a powerful adsorbent of copper and heavy metals. CupriSorb will remove copper more rapidly and efficiently than carbon and is thus ideal for emergency copper removal. It extracts all types of copper from water and, if in continuous use, from the gravel/substrate bed as well. CupriSorb will allow maintenance of invertebrates in copper-treated tanks by removing copper leaching from substrates. A 100 mL bag is adequate for up to 60 gallons and removes over 3,000 mg of copper or 12 ppm in 60 gallons. It may be regenerated repeatedly. Marine or freshwater use.
CupriSorb can be used by placing in a canister filter, media filter, high flow area of a trickle filter or sump. The 100 ML size comes in a filter bag.
