Cupramine is a superior copper treatment option for eliminating a variety of external parasites such as ich and velvet. Cupramine effectively eradicates Oodinium, Cryptocaryon, Amyloodinium, Ichthyophthirius, and other ectoparasites. It is superior to copper sulfate, chloride & 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.



  • Copper treatment for external parasites
  • Active at low concentration (does not precipitate)
  • Bound on amine so it is not as toxic to fish
  • 100% Removable with carbon or Cuprisorb


Available in Seven Sizes

  • 50 mL

Directions for Use

  • Before treating, remove all invertebrates or, preferably, treat in a hospital tank. Invertebrates are intolerant of copper treatments and this medication should not be used in systems containing them.
  • Turn off UV filters, ozone filters, and remove any chemical filtration such as MatrixCarbon and Purigen.
  • 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.



  • If the bottle has a dropper cap, use 20 drops (1 mL) per 40 L (10.5 US gallons) the first day. On non-dropper caps, each inner ring is 1 mL.
  • Wait 48 hours, then repeat dose.
  • Test Copper levels after each dose. Although most fish tolerate Cupramine to 0.8 mg/L, it is not advisable to exceed 0.6 mg/L copper.
  • Leave at this concentration for 14 days. Do not redose without testing.


Finish the Full Treatment

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’t see parasites on the fish!


After Treating

Cupramine can be removed using carbon or CupriSorb. Leave the copper-absorbing media in your tank for at least a week after the copper concentration has reached 0 to ensure all traces of the medication have been completely removed.
