I have a 250 gallon water garden, using a pre-formed pond liner. I gave
the pond its spring cleaning about a month ago, re-filled it as I usually
do, using part well water, part rain water. I have had string algae every
year in the past, but not to any great extent. This year, it is threatening
to take over the pond. It is clinging to the sides of the pond, looks like
it is already three or four inches thick. It is covering the bottom of the
pond, and clinging to every object in the pond, water lilies, etc. I have
lots of plants, a barley pad in place - in short, doing things the way I
have done them every year, but the algae is unbelievable. Any suggestions as
to how to get rid of it ? A few years ago I read about using a solution of
hydrogen peroxide, I think, but I cannot find the article. I would
appreciate any suggestions you can offer. Thanks. Pete
