These are thrown into the pond and sink. He tells her this is to deter algae. Has anyone ever tried it and I wonder if it would work on the accursed duckweed? I'm sure I have seen ponds and water features with copper coins thrown in and still have algae floating in them, ok the copper comtent is less than it used to be but there are a fair number of older ones around. G.Harman Not enough copper in too much water, I'd think. Unfortunately, the book doesn't go into the ratio of copper to water and fish! -- Sacha www.hillhousenursery.com South Devon www.helpforheroes.org.uk |
