Condensation off copper pipes bad?

[11f150]

I was reading a thread today where someone was installing a frag tank in their basement and had copper water lines above the tank running along the joists. They installed foam insulation boards under the copper pipes to stop any dripping from the copper pipes from condensation build up. My question is can copper really get into the condensation and potentially contaminant a tank under them if it drips into it?

Quick answer is probably NO, but if you had a lot of drips, (thinking rain) maybe.
Reference:
Copper was soluble at all concentrations in pH 5.5 distilled water. At higher pH values, the amount of soluble copper was a function of both pH and the total copper concentration, with a maximum of 4 mg/l soluble copper at pH 6.5 and a maximum of 1.3 mg/l soluble copper at pH 7.4.

Another way to think of this; A liter of drops could add 4mg of copper to your tank.
4 mg/ total tank gallon(s) = negligible Cu. and that is with a liter of rain drops.

Condensation is outside moisture forming on the pipes. So it would be whatever is in that water + copper oxide (green discoloration from copper pipes) combining and dripping into the tank.

Of course if the water doesn't get into the tank, there is no problem. A couple of drops also won't do anything. When the hobby started and we didn't have liquid copper we used to add pennies to the tank to cure ich.
