Review on 🔒 Seachem Cuprisorb 100ml: A Powerful Solution to Remove Copper from Aquariums by Tina Price

I don't know what Cuprisorb does, but it doesn't remove copper. This is what my aquarium looked like two days after I put it in my filter. I called their tech support and they tried to help but basically said it was an unrelated event due to high phosphate levels. I've tested my water 3 times, zero phosphate and still positive for copper. I had to do a complete water change to salvage what was left. Eventually I lost two fish and a snail, and the survivors look like they'll be joining them soon. Just take RODI.
