Live rock problem

[Fishmad]

I have a 100L hospital tank were i keeping some live rock, my 2 regal tangs got white spot, put them in the hospital tank, treated tank with Cupramine by seachem, but now can i use live rock in main tank with corals and invertabrates, any advice would be much appreciated

copper will kill inverts, and any tank or rock exposed to it is unusable from what i have read.

I agree with forestal you should NEVER use LR when you treat with copper, it would be fine to use in a FO tank but no inverts.

The rock will absorb copper and slowly release it into another tank if moved - a sand bed can as well.

I thought that might of been the case but was unsure, better to be safe than sorry thanks for the advice

Copper & Reef tanks.

I would personaly never put the liverock that you treated with copper into any other reef tank. It will probably be toxic forever. Remember very small trace amounts of copper measured in parts per billion can be fatal to all the microscopic life forms on mature liverock! The EPA has banned any and all types of copper from being used any where minutely close to any body of water in the U.S. My 2 cents. "Ron of Triton"

Out of interest, why are you keeping LR in a hospital tank. The whole idea of a hospital tank is to run in completely bare so you can disinfect it at any time. If you need to put some hiding places in, just use some plumbing parts. Then run a machanical filter with some filter media matured in with the odd slice of shrimp left to rot in the water. Much more cost effective than wasting LR
