you can still get them though. I got tons of them, I think its anything before 82, dont quote me though.I agree about copper sulfate as a great treatment.
When I was a kid first keeping fish in the 1950s, and pennies were still made of copper, one of the common treatments was to throw some pennies in the tank, and if I can remember that far back, it actually worked. It won't now, because pennies are no longer copper.
hi guys, the ich is still showing on the fish, Ive been doing about 90 drops 3 days on then 3 days off in my tank with temp around 81. Its a 125 gallon. 25 percent water changes almost every day. Do I need to just keep it up till its gone?
