Seachem Laboratories Cupramine Active Copper - 100mL Information

Product Manuals & Documentation

SeaChem Cupramine ™ effectively eradicates ectoparasite of both freshwater and marine fish. It has all the advantages of copper sulfate and chelated copper, but not the disadvantages. Like copper sulfate, it is fully ionic and effective at low concentrations. The cupric (Cu+2) charge is fully active. Like chelates, it is safe for fish and is not precipitated in the filter bed. Unlike both, there is more than a 4x concentration gap between the minimal therpeutic dose and the toxic dose. Unlike copper salts, it is stable in the aquarium, and, unlike chelates, it is easily removed by chemical filtration. Unlike other copper products, it is both highly effective and safe in freshwater as well as marine water. It does not damage the filter bed. Cupramine™ contains 10,000 mg/L of copper and 100 mL treats over 500 gallons. Do not use in conjuction with ParaGuard™. Test for copper with our MultTest: Copper™ kit. Marine or freshwater use.

Caution: Turn off your UV sterilizer while treating with Cupramine. UV will break up the ionic bond in Cuprimine; causing it to be much more toxic.

Cupramine Works

Reviewers Rating Excellent!

Experience Level: Intermediate

Comments: I am still treating my DT, but there is no signs of any ick. The product works as stated,and is safer than copper for the fish. I will be treating for 28 days which is the optimum length that I have read in some articles. This makes sure that any cysts that hatch are eliminated. I was using Paraguard but it is not as effective.

Fish stopped eating.

Comments: I used Cupramine on my large Queen Angel. Fish slowly stopped eating the second day dosing (I did half dose increments). At 0.5ppm, fish looked & acted normal but refused to eat. After 3 days of no eating, I decided to perform a 50% water change and added activated carbon. By the next day the Queen Angel had an appetite again. I may use this product again and with other fish.

Comments: As you might have imagined I bought this product in order to treat for ICH in my quarantine tank before introducing new acquisition to the Display Tank. The product works great, and its a lot safe than other copper medication I have tried. They have great customer support when I contacted them with a question! Overall I cant complain it has been great!

Seachem Cupramine

Reviewers Rating Excellent!

Posted: 6/5/2011 from RIVERSIDE, CA UNITED STATES
5.0 5
Experience Level: Intermediate

Comments: Works great for SW Ich. I recommend this for it over Paraguard to make sure it does the job right the very first time. I've used this in a FOWLR tank with LR and LS (which isn't the recommended method of treating fishes) but I didn't have a big enough tank to QT 3 triggers/2 angels/3 tangs/8 chromis and other misc fishes without major ammonia spike and increased stress on the fish. With LR/LS in the tank, it took about 2.5x the amount recommended since the LR/LS absorb a little. After a week of dosing, I was able to get a stable reading of .5. I treated for a 4 week period to make sure ich was eliminated. After using about 3 Polyfilter pads to remove the Cupramine in my 125 (150 gal total) for about two months, I introduced two cleaner shrimps/emerald crabs/ RBTA and soft corals into my tank without any issue with Copper poisoning. I highly recommend Seachem's version of copper treatment for ich!

Excellent product

Comments: I think this is a great product. It's easy to use and 100% kills ich, which is what my intentions were for it. All it takes is two weeks of monitoring your copper levels with an appropriate test kit. I used Seachem's copper test kit and had no problems. Two weeks later, my fish are all ich free and happy. I have some delicate fish and none of them had any problems with Cupramine, which has to do with it being an organic chelated copper that is very easy on fish. Traditionally delicate fish like puffers do very well with a copper product like Cupramine.

Comments: I've been using this product, exclusively, to treat all my new fish which have been exposed to ich. It works well, and I haven't had any signs of the parasite since I started treating my fish with it 6 years ago.

Worked for marine velvet

Reviewers Rating Excellent!

Posted: 1/19/2009 from MELBOURNE, FL UNITED STATES

Experience Level: Intermediate

Comments: I ended up with marine velvet on a pair of charming true Perculas in the quarantine tank. The male clown was in worse shape and looked miserable, I didn't think it would make it. The funny thing is that I realized that I was actually attached to those little clumsy fish. After learing about treatment options, I performed a 5 minute fresh water dip along with formalin and malachite green solution (using Ich-Rid+, Kodrdon brand). The fresh water dip gave immediate relief to the male clown. I think the gills were infested with parasite and fresh water + formalin dip discarded a good portion of them. Then I used the Cupramine copper according to the Seachem instructions with concentration of around 5 ppm. The treatment worked very well. Quarantine tank's temp was around 75 F. Due to the severity of the parasite infestation, the male clown lost some scales and was sort of scarred for a while, but they are brought back to health, scars are gone, and they act like two little piggies begging for food all the time. No immediate ill effects were noted with this product. It saved my fish.

Best Copper on the Market

Experience Level: Intermediate

Comments: I've had very good results using this product to treat marine Ich. Make sure to purchase Seachem's Copper test kit to ensure you are treating at the appropriate levels, as this stuff is highly potent and can kill your fish if overdosed. Do not use this product if treating Flame Angelfish. They cannot tolerate copper well even at the lower dosage. Other than that, this stuff works.

100% Effective

Reviewers Rating Excellent!

Experience Level: Intermediate

Comments: Used Cupramine in my quarantine tank to treat ich that was infesting my powder blue tang (quarantined all my fish). Ich was no longer visible after the third day and the tang started gaining returning to a healthy weight. The Cupramine did make my skimmer produce thick clouds of microbubbles, but otherwise had no ill effects on any of the livestock and is a small price to pay. Definately recommended.
