Re: copper in the water
Karen Randall wrote about not being able to grow Valisneria because of its
sensitivity to copper.
Karen, I used to be in Boston, and the water there had 5 mg per liter of
copper. After standing in a tank for a month, that water would kill a
snail in 30 minutes and a fish in four days. I figured that other people
kept their fish alive only because they used activated charcoal in their
filters that captured the copper. I didn't want to do that, so I solved
the problem by borrowing some 5 gallon plastic containers from a freind,
and going to the outflow from one of the local reservoirs and collecting my
water there. I filtered the water through sand to catch any hair algae
that might have been picked up and kept it in a covered aquarium. It was
excellent water and I never had any problems with it. In fact, I started
wondering if all that copper was OK to drink, and I began drinking the
water I had collected. No problems, and I am still here to tell about it.
