GC with copper safe?

[Cflip]

my fish are on the last stretch of QT. Can I add GC to the tank with copper power? Then wait 5-7 days and do a water change without copper? By then it will be 30 days. What’s the amount for a 10 gallon tank? They aren’t showing any symptoms just prophylactic for now.

I always wait until after the copper is over and removed to dose GC. It's pretty tough on the fish's immune system to combine copper and other meds, unless there is a great need to address disease or parasites. Then the risk can be worth the potential results. In a 10 gallon tank, you usually dose one packet of GC into the water column.

I have done it several times but out of need rather than as normal course. I saw no issues other than the prazi did not kill my flukes either. But out of normal quarantine I would not double up. 1 dose than 7 days later the second dose.

Pre-dissolve it before adding. There will be pieces of the meds floating of you don’t.

I've done it many times without issue. Just make sure you aerate the tank well.
