Copper wire to deter algae in ponds
In The Garden of Evening Mists, the woman learning from the Japanese
master is set to making balls out of copper strips. 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? -- Sacha www.hillhousenursery.com South Devon www.helpforheroes.org.uk |

Copper is great if a clear but near sterile pond is wanted.

The Dutch used to put powered copper electrodes in the water of their large boat houses to reduce weed. It's probably banned now. There are no fish left in the IJsselmeer because either a) Over fishing - government version. b) The water is too clean, so no food for the fish to feed on. Fishermen's version. There is going to be a three year ban on fishing. -- Martin in Zuid Holland ====================================== Martin I hope we are not getting confused with "Cathodic Protection" which is a whole different ball game.

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? A strip of bare copper wire along the ridge of a house roof is supposed to keep the roof clear of moss. I'm not quite sure what form of life moss is, but copper is poisonous to many life forms (eg it's a popular fungicide, and above a certain concentration can inhibit plant growth) so it wouldn't surprise me if it prevented algal growth in ponds. But it raises the question as to what else it would kill, animal and vegetable. You might end up with a sterile pond. Controlling algae is better done by controlling the nitrate levels in the pond by not (over)feeding the fish. Duckweed may be similarly controlled. If the fish aren't fed, the nitrate levels in the water will be low so won't encourage the DW, and the hungry fish will eat what's remaining. No DW or algae problems in my pond. If we don't feed our fish, they eat the frog spawn. ;-( We're feeding lightly now. -- Sacha www.hillhousenursery.com South Devon www.helpforheroes.org.uk |

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.

Yes, I agree, in parts it was a bit convoluted and 'mystic' but nonetheless I enjoyed it and it drew me in. A friend had read it and recommended it to me, mainly thinking of the garden aspect, I suppose. -- Sacha www.hillhousenursery.com South Devon www.helpforheroes.org.uk |

Is that what's been banned because it damages sea creatures? Only by the Dutch in inland waters. Antifouling containing TBT is the chemical that is banned everywhere. Ah yes, that's what I was thinking of. I'm not sure what the situation is with commercial boats/ships often they are excluded from this sort of ban. No idea how much it's used nowadays. I just knew it had been used to protect the hulls below the waterline and to deter weevils, barnacles etc. -- Sacha www.hillhousenursery.com South Devon www.helpforheroes.org.uk |
