SeachemCupramine Copper 250ml

Works great for ridding fish of ich, and many other common parasites. I've seen a lot of reviews blaming Cupramine for their fishes death. I ramp up the dosage in 4 parts(not 2 doses like the bottle recommends) over the course of a few days and keep every new fish in the medication for 4 weeks. I've put over 15 tangs and 30 other fish through this and have had nothing but luck. Make sure your fish is eating well before dosing and keep an eye on them and you will have success. Do research on your fish to make sure none of them are copper sensitive.

Fish came down with a bad case of ich in my planted rainbowfish tank. The ich made it past the quarantine process and ended up in the DT. I treated two tanks simultaneously, one with Hikari Ich-X (malachite green and formalin) and the other tank only with Cupramine. The tank with Ich-X eventually cleared after approximately 6 days and daily treatments, two lost fish and tank stained blue green. The other tank that was treated with Cupramine had no losses (and there are Amano shrimp, Otos and Corys int hat tank). Started with the recommended dose of 0.25 mg/L for freshwater dosed over 48 hours. Since the fish showed negative signs or stress, I upped the dose to 0.5ppm over the next couple of days. I used a Seachem copper test kit and measured CAREFULLY as I have read reports of overdosing nuking fish. After 10 days there are no fish or invert losses, fish have no evidence of ich both on the skin or in the gills (no labored breathing). I will complete the recommended dosage time of 14 days and add Matrix carbon to the filters to clear out the Cupramine.The Pros of using this medication are:- It does not stain like Formalin.Malachite Green treatments- Only one treatment needed (dosed over a few days) as the medication remains in the tank and sits there in the waiter waiting for the disgusting ich swarmers to hatch so they can be annihilated!- Cost effective as I only needed about 24ml in a 125 gallon tank (plus 5 gallons of filtration volume) to achieve a treatment dose fo 0.5ppm. I would have had to dose 65ml PER DOSE of Paraguard , DAILY for 28 days! Thats 1,820ml of Paraguard!!!Cons:- DO NOT use if you are lazy, this requires measurement of copper to confirm dosage.- Can't think of any other cons to using this product. I will switch to using this instead of Formalin/Malachite in my quarantine tank from now on.

I use this for my fish quarantine tank. No fish enters my DT without being treated with this and PraziPro. I choose to do my dosing in 1/4 doses, every day or every other day, depending on the fish. This is one of the only known products to eradicate cryptocaryon irritans (sometimes referred to as "marine ich"). Other options include tank transfer method, hyposalinity, chloroquine phosphate, or other copper based medications. This copper based medication is better than others because it does not soak into the equipment and the seals of the tank. This medication is easy to remove by using Seachem Cuprisorb, or activated carbon.One hint: If you have time, set up a quarantine tank with water from your DT. Put some type of sponge filter in the QT and continue to seed bacteria for a few weeks. This should establish enough good bacteria to handle the Cupramine. If you don't have enough bacteria in the QT, you are more prone to killing off the bacteria and having an ammonia spike. This method works very well for me. If you have to do this in a hurry, please keep an eye on your ammonia. Seachem Ammonia Alert works great for this purpose. It lasts for a year and just hangs on a suction cup in the tank.

I gotta say this stuff works! Treated a powder brown tang a clown and yellow tang in my 20 gallon QT, got a lot worse before it got better which is totally normal, let the cupramine do its job and it will eradicate ich off your fish and In your system if your a fish only. I slowly ramped up the dose double the amount of time listed on the bottle, copper is poison and should be slowly introduced to your QT / DT.

Cupramine is a highly effective copper based treatment for Ich -- a truly aweful disease that was about to wipe out all the goldfish and Koi in my tank. It's a large tank and I appreciated that it takes so little of this treatment. It's very economical which is important because with Ich the whole tank must be treated, not just the fish so you cannot use a small hospital tank unless you are willing to keep the fish in the hospital for many weeks (the parasites will eventually die in the display tank without treatment if there are no fish for them to infect but it takes a while to be sure). You can see the fish do not like the medicine. After the first half dose two smaller Koi died from the treatment (ironically they had been doing best against the Ich before that). I was quite worried about what would happen after the second dose was added, but there were no further fatalities even after the second dose though the fish were lethartic and stopped or slowed eating. Obviously they felt sick. But once the Ich was gone (it takes a few weeks for all parasites to enter their vulnerable life phase), I started the water changes and all the fish bounced back. Cupramine is strong medicine for a bad disease. It's not to be used lightly but effective if you need it and very reasonable in cost even for large tanks. A side benefit is it's tough on algae.

Tried copper aid and just couldn't get the levels to stabilize where they needed to be and never actually cured crypto on a regal tang, waisted two months with copper aid. Switched to this and within two weeks by all accounts it was gone and fish were doing better in QT tank. Levels were easy to attain and hold and fish responded within days not weeks. Fish are now back in main DT and doing very well with no signs of crypto. Tried 4 products including this one and this was the one that fixed the problem.
