I have "recovered" a tank that had a Copper solution used in it and
stained the silicone blue. Afterwards ghost shrimp thrived in that tank.
Muriatic (concentrated Hydrochloric) Acid, the kind used for etching
concrete will dissolve out the remaining Copper. Neutralize the tank
with strong Thiosulphate afterwards.
I would NOT recommend anyone who isn't familiar with the safe handling
of strong acids to even think about it though. Cu Sulphates and Oxides
can also be reduced to Chlorides with standard bleach but plan on having
your tank sitting full of fixer for a week or so after.
