If I were going to use copper, I'd use copper sulfate. It's a pain to use, because you need to test the copper level at least once a day, twice is better. Then you have to add enough copper to bring the level back up. It's very effective, but also very toxic. If you use any type of copper, use a quarantine tank, and do not use live rock or a sandbed in the tank. |
I have maintained hypo for 8 weeks at a time, twice
