Just ran a couple of searches, most sites list 6-8 weeks, 8 giving a better chance of clearing it from the tank. Higher temps speed up the process, but might be harmful to corals.

Well some bad news... lost another fish.

Today it was my Flame Angel. That brings the death toll to 4. :cry:

Did a 5 gal waterchange and added a little more copper to the tank.

Fingers crossed cuz I'm running out of fish! :sad::sad:

Are you measuring copper?

:cry:
+1 to measuring copper. A seachem kit is cheap enough

that sucks man, I am sorry to hear.. hopefully you can rid your tank of the problem. :( poor buggers

Yes I am testing for copper. Just had add a little to replenish what I removed.
