Unfortunately I am now setting up a hosp. tank for my 2 remaining fish that haven't died from a major ick outbreak this week. I've lost 4 so far and 1 of the remaining fish looks bad. That being said I've never set up a qt tank before (obvious huh?) and never used copper. What brand or type of copper should I used in the QT? The only brand I can find so far in the LFS is Coppersafe by Mardel. Anyone use this? or can you suggest a better option that I should order? Thanks in advance for your help.
