HI there.
Okay i have no idea for that product. Does it not say on the back of it?
Can you get your hand on some seachem stuff? I use Cupramine as it is a little easier on fish.
Here is the instructions on the back of there bottle:
DIRECTIONS: Remove all invertebrates. Turn off UV sterilizer; remove chemical filtration. Use 1 mL (top mark of enclosed dispenser) per 40 L (10.5 gallons*) the first day, wait 48 hours, then repeat for a total dose of 0.5 mg/L (in freshwater, use half dose). Leave at this concentration for 14 days. Do not redose without testing (MultiTest: Copperâ"žÂ¢). Do not use in conjunction with any other medication. If tank has ever been treated with an ionic copper (e.g. copper chloride, sulfate or citrate), test copper level after initial dosing. Although most fish tolerate Cupramineâ"žÂ¢ to 0.8 mg/L, it is not advisable to exceed 0.6 mg/L copper. Remove with carbon or CupriSorbâ"žÂ¢.
You need to be carefull with copper as high levels can kill fish. The on ly time i have used Cupramine was when i got my hippo who did not respond to hypo.
Make sure you test for copper levels in your tank before you ad more.
