Seachem Cupramine

Seachem Cupramine is used to effectively eradicate external parasites such as Oodinium, Cryptocaryon, Amyloodinium, and Ichthyophthirius in both freshwater and marine fish.

  • 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

Seachem Cupramine effectively eradicates Oodinium, Cryptocaryon, Amyloodinium, Ichthyophthirius, and other ectoparasites of both freshwater and marine fish. 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.

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™ is easily removable with chemical filtration. It is highly effective and safe in freshwater as well as marine water.

Types of Infections Treated: Parasitic 

Directions

Before Treating

Remove all invertebrates - 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 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.

Treatment

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 a 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 Copper). If the 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™ to 0.8 mg/L, it is not advisable to exceed 0.6 mg/L copper.

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.

In case of eye exposure, promptly & thoroughly wash your eyes with water & seek medical attention.

Great quality. Easy to clean. Nice appearance.
Color: Red, Size: 4.3-Quart
Solid, heavy pot for cooking and baking. I bought it mainly for making soups, stews and breads. I have only tried soups thus far. The pot cleaned up very easily. The bottom of the pot heated uniformly. Nothing was stuck to the pot when I was simmering on the glass top stove. I have not had the chance to bake yet, but seeing how evenly it held heat while cooking, I am thinking this will be perfect. I bought the red color. It gives a nice pop of color in my kitchen. This pot will probably last me a long time. I would buy one if I needed a replacement, or a gift for someone.

Great quality for price after 3 years of use
Color: Matte Navy, Size: 6-Quart, Color: Matte Navy, Size: 6-Quart
I’m 3.5 years in and use it weekly. So far it’s been a great product especially for the price. We are really into soups, roast, and I bake bread a lot. This thing is amazing and a great quality. It’s easy to clean, does great in the oven, and stands up great to constant use. I only have a small amount of staining at the bottom, and a couple scratches from metal utensils. The lid is solid and the handle is really secure still, which is a problem I’ve had with other brands I’ve tried.

Quality product
Color: Navy, Size: 6-Quart
I absolutely LOVE my Dutch oven! The reduced cooking time for certain cuts of meat for stews, pot roast, etc., is a definite game changer!! The meat comes out so juicy and tender. I made curry and did the "burning" of the curry and was hesitant because I didn't want the pot to be stained. There were no stains left at all. I've used it numerous times since purchasing and it still looks new. It's very durable and the color is beautiful. If you're looking for a functional, quality, and durable Dutch oven without breaking the bank, this is it! I highly recommend.
