Copper leaching question.

[USMA36]

I have a qt tank that was used one time for copper 6 months ago. I want to use this tank as a coral at tank and to hold some live rock rubble for use as frag plugs. I have read some reports that say the silicone can leach copper. What are the chances my live rock rubble will absorb that leached copper and kill inverts when I place that rubble as frag plugs in my main tank?

Rock will absorb and release copper. A tank/equipment will not. Chuck the rock (anything calcium based that was in the tank when you used Cu)....everything else is fine to re-use.

Silicone neither appreciably binds nor leaches copper.

The concern is deposits of calcium carbonate and organics, that do bind copper.

Thank you. The rock was added long after the copper.

Yup this product works well. Add this to polyfiber pads on a wave maker, carbon, and GIANT water changes, and you'll soon get there. Replace all media after the first week. Repeat after two weeks. During that time I would have done two or three 90% water changes.
