It is superior to copper sulfate, chloride &amp; citrate: it is non-acidic, less toxic to fish, remains in solution, and does not contaminate the filter bed. It is superior to chelates: it is fully charged (ionic), active at low concentrations, and is removable with carbon.<\/p>\n<p>There is more than a four-fold concentration gap between the minimal therapeutic dose (0.2 mg\/L) and the toxic dose (0.8 mg\/L). Cupramine\u2122 is easily removable with chemical filtration. It is highly effective and safe in freshwater as well as marine water.<\/p>\n<p>Cupramine\u2122 is appropriate for treating a variety of ectoparasites of both freshwater and marine fish. Below are some of the more common infections treatable with Cupramine\u2122. Be aware that many diseases and infections share similar physical and behavioral symptoms, e.g. clamped fins, lesions, loss of appetite.<\/p>\n<h2>Key Benefits<\/h2>\n<ul>\n<li>Copper treatment for external parasites<\/li>\n<li>Active at low concentration (does not precipitate)<\/li>\n<li>Bound on amine so it is not as toxic to fish<\/li>\n<li>100% Removable with carbon or Cuprisorb<\/li>\n<\/ul>\n<h2>Directions and Care<\/h2>\n<p>Remove all invertebrates &#8211; these are extremely sensitive to copper and will not tolerate treatment with a copper-based medication. Turn off UV filters, ozone filters, and remove chemical filtration like MatrixCarbon\u2122 and Purigen\u00ae. Do not use in conjunction with any other medication. Do not use any products which contain reducing agents (conditioners, ammonia binders, etc.) while using Cupramine.<\/p>\n<p>If the bottle has a dropper cap, use 20 drops (1 mL) per 40 L (10.5 US gallons) the first day, wait 48 hours, then repeat. On non-dropper caps, each inner ring is 1 mL. In freshwater use half dose. Final copper concentration is 0.5 mg\/L (0.25 mg\/L in freshwater). Leave at this concentration for 14 days. Do not redose without testing (MultiTest\u2122 Copper). If tank has ever been treated with an ionic copper (e.g. copper chloride, sulfate or citrate), test copper level after initial dosing. Although most fish tolerate Cupramine\u2122 to 0.8 mg\/L, it is not advisable to exceed 0.6 mg\/L copper.<\/p>\n<p>Ich, velvet, and many other parasites spend a large portion of their life cycle as a cyst that is immune to medication and hiding in the substrate of your tank. Remember that you need to finish the full treatment even if you can\u2019t see parasites on the fish!<\/p>\n<h2>Storage and Safety<\/h2>\n<p>Keep the container tightly closed in a cool, dry place. Keep out of reach of children and use only as directed on the product label.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cupramine\u2122 effectively eradicates Oodinium, Cryptocaryon, Amyloodinium, Ichthyophthirius, and other ectoparasites of both freshwater and marine fish.
