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.

Seachem is awesome!

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.

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.

This worked great for getting the copper out of my tank after a medicine treatment. I just sticker by the intake of my filter and the tank was reading 0ppm in no time. I left it in for a couple extra weeks to be sure. It's been a few months after finally removing it and I just did a whole tank reset, stirring up quite a bit of gravel as I planted new plants. Just out of curiosity I tested for copper and it still ready 0ppm! Easy to dry out too, I just set it on my patio table outside for a few days, turning it over every day. Great to have on hand if we need to dose with copper containing meds again.

It's really hard to estimate how much is in this package in terms of VISUAL volume. And when you get it, you may wonder if it will work on X-size aquarium. It's small enough to fit in many Whisper filters, but since copper isn't all that common anymore (even in medications) it can handle very large aquariums too. It appears too small for many aquariums out there (you might wonder if it can even cover 30-gallons) but it can do the job. The best part is it's regenerable, so you can use it every time you have to use copper meds, to get the copper back out after treatment. Or if it's used in a very large tank and seems to stop removing the copper, take it out, soak it in the muriatic acid solution, rinse, and plop it back in. So a small amount can really go a LONG way.

seems to be working, but a good bit slower process than i hoped.
