It's possible that there could be some metals in the water. Since the OP is from Staten Island, I would assume he/she is on municipal water - would be surprised if they posted back and said they were on a well. Going with the city water assumption for now, the other culprit for adding metals to the water is past use of copper-based algaecides or ionizers.
Fink0517: In addition to responding to Texas Splash's questions, please indicate if you are aware of past use of algaecides and/or ionizers.
