You HAVE to get this if you have snails and any copper in water
my snail has been so active ever since i added some of this to the filter output. I don't have an enormous tank so I cut open the sleeve and poured 3/4 out to save for later. I clipped the mesh sleeve shut and put it in where the water comes out of the filter as that's the only spot that has room. a must if your tap water contains any residual copper.

Effective Copper Removal for Aquatic Systems
Effective product for removing copper in an aquatic system. A year ago, I treated a small tank with copper. I have a small tank that uses the eLive Duo Filter. For more information on that filter, please follow the product link on Amazon Elive Aqua-Duo Dual Purpose Aquarium Filter . Snails got accidentally introduced to the tank when I added plants. To get rid of the snails, I used Cupramine. I got rid of the snails but now the sand in the tank and the expanded clay media in the Duo Filter are contaminated with copper. This is no problem as long as you don't want to keep shrimp and clams. A year later, I decided to try keeping freshwater clams. First step, remove the copper. I put one small bag of cuprisorb in the filter and let it run for three weeks. The water is testing zero amounts of copper after three weeks. I did not think copper can be removed from this system due to the expanded clay media in the Duo Filter. But it worked. This product is effective. Highly recommended.

Works Like it Should!
I had a really bad outbreak of ICH in my reef tank and had to move all my fish to QT to treat with copper. Ran the cuprisorb as per instructions and it removed the copper quickly and effectively. Price is competitive for what you get. Works well with Seachem Cupramine! Would definitely recommend.

Works
These work well, as they were designed to do. I used these in a tank that had previously been exposed to algaecide and copper-based treatments. My daughter wanted mystery snails, so after a water change, I used these to absorb any raining copper or toxic metals. It never turned colors, so I think that was a good sign..... I used a copper test kit just in case, it came back negative for traces. So yay! She now is enjoying a rather happy mystery snail who is quite satisfied with his home lol. I also should say I used it in a 20 gallon, so they CAN be used in smaller tanks. However, I think it'd be helpful if they offered different sizes for different tanks.

Removed my Chelated copper!!
The item I received is not what is shown, but I knew the picture must have been wrong. The canister pictured holds way more than 100ml. What I got was a small 100ml self packaged bag that fits perfectly in my Aqua Clear hang-on filter. Originally, I got Ick in my freshwater tank. So I went to the closest pet store and got the only medication they had, chelated copper. So I come to find out that with this wonderful medication in my water that I can't have any freshwater shrimp. Bummer. So I thought the carbon would remove the medication like all the other Ick medications but not so with chelated copper. It stays forever. So anyway I got a water copper test kit to see where my copper was at. It wasn't too bad but before I put this in I was reading about 5ppm. After a week with this in my filter I now have no copper in my water. The resin has turned a bit blue as it said it would when it absorbed the copper. I'm happy and I have shrimp living happy in my tank now just 2 weeks after adding this to my filter.

54 g vs 100 g stated. Some say it does not remove copper for marine tanks
First, it is stated 109 g but weighing it it comes at 54 g. Second, mixed reviews on the internet regarding the fact that it may not remove Cupramine from the hospital tank while on the Cupramine bottle it is mentioned to use Cuprisorb to remove copper. Trying today, we will see. Third, emailed Seachem, never heard back. Fourth, Rowarcarbon used to remove copper, been in the filter for a month, zero change in copper level. Why do they sell Cupramine stating to use Cuprisorb to remove Cupramine after treatment and mention that Cuprisorb is only to remove copper from freshwater tanks. Confused…
