I would, respectfully, disagree with the above.  We buy live rock becaus
it is just that, filled with lots of living critters.  By scrubbing and
washing in fresh water you are going to kill a lot (most) of them.  I
would doubt that you will kill even close to all of the parasites on
the rock (think of all the nooks and crannies)....  Additionally, why
even try?  This live rock came from nature.  Nature has parasites.  That
is just the way it is.  If you fish are healthy you should have no problems
with putting live rock in unless it has a lot of rotting matter which
will foul the tank.  For this reason it is best to "cure" the rock
first which basically means you wash/rinse it off with seawater first
and then allow it to sit for a week or two.

It is generally best to add all of your live rock at one time to avoid
the ammonia spikes that come from adding fresh rock.  However, if you are
getting rock that is -definately- cured (like stuff that has been in a store
for a few weeks), then you can add it at will.  Beware of adding large
amounts of live rock when the tank is populated already because you can
poision the tank with ammonia from rotting material if it isn't cured.

I wouldn't worry about it so much.

The above is correct.  Copper once in a tank is usually there for
good.  You can try soaking all the corals and treating with a copper
remover, but I personally would not chance it.

I strongly recommend an RO unit for your water.  Not only will it
remove the copper, but will also remove nitrates, etc for filling
your tank and doing water changes.  My personal favorite is SpectraPure.

Kole Tangs are WONDERFUL!
