Safe copper level for snails

[khull7]

I had an ich problem in my tank about 2 months ago, I removed my invertabrates and treated the fish with copper. All the fish have been fine now for about 5 weeks.
What is a safe amount of copper to return my inverts to the tank?

Copper should be undetectable to be invert safe. In fact, some will say that you can never put inverts back into a tank that has been treated with copper. You might consider making the tank a dedicated hospital/quarantine setup and getting another display tank.

Yup, undetectable,...and depending on the test kit you are using, it may be hard to tell. But at a minimum a home test kit should not register any copper. I also definitely discourage treating a display again with copper. Do you have LR? If so, do you see any sort of inverts in the tank? Pods? Worms?

I now have a 60 gallon tank with about 80lbs of LR , my blue and red leg crabs are still alive and working hard, we have seen 2 bristle worms that are about 1 inch long each.

Copper test results?
I mean, you could always try. One thing that I would like to see is some sign of "reproduction" if you will. Increasing numbers of pods, microbrittlestars, etc. Larvae are typically very sensitive to copper so if they are surviving, that is a good sign.
