Copper Really Lasting for 30 Days?

[redsea]

Hi all,

On my copper bottle it says that it treats the tank for 30 days. Does this mean that the amount of copper will stay at the level it was at when I first added it for 30 days? I just want to make sure my fish are ich-free before going back to the 34g.

Thanks everyone!

I read that if you do water changes during that 30 days then you need to dose the new incoming water to maintain copper levels.

The copper will stay in the tank until you remove by water changes or a copper removing media. If you keep it at a theraputic level it will last indefinitely.

That makes sense, thanks Larry!
