SeachemCuprisorb 100ml

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.

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.

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.

I first used cuprisorb years ago for a marine tank, kept it in till the bag wore out, marine life, specially my cleaner shrimp thrived. a few years of back to back storms decimated my tank and I converted it to fresh. some how I got some copper in the water system, this took care of it. I have it in a safe moist spot now, as my fresh plants need some of the minerals it will remove beside copper.Unless you have a lot of copper/metal I can't see how the bag would ever need a recharge, it works and works, and frankly, I would just replace it as there are noxious chemicals in the recharge recipe/procedureThe newer bag, is thinner and had better water flow, a better design than what I knew years ago, was happy with the new bag, and the stuff inside

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.

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

I placed this in my filter (power filter 10) and it barely fit because the bag is quite big for my filter. However, it worked perfectly. I had it installed for two days and it worked perfectly. I tested my copper levels using API's kit (I know it kinda sucks) and it came out with 0ppm of copper. I am very satisfied with this product and would only hope that they also include a smaller pouch for small filters like mine. However, that isn't much of a problem.Highly recommended.

Amazing!!! Don't waste your time with products that claim to kill ich without copper. Use copper and then use this. It works 100%. I wasted my time and lost some live stock. I added my corals back to the main tank in 2 weeks after installed this substrate. I dropped this to a small filter bag before I used.
