Hydroponics will absorb whatever is in the water, if there is nickel in your tap water, fill up the reservoir with filtered water. I use one of the tough storage totes and put cardboard over it so light doesn't get in there. For a decent size set up you might need 20 gallons of water every couple of months. One day I'll post about it :)
