There have been a couple of posts lately about algae
described like this. Or describing algae that forms in lumps that
break up and dissolve on contact. Or describing algae the has a
really disgusting smell ...

Any of these posts could in fact be describing
cyanobacteria, also known as Blue-Green Algae. Cyanobacteria, as
the name says, is more accurately a bacteria than an algae.
Though it certainly appears like algae it is best to think of it
as bacteria that has developed the ability to produce its own
food through photosynthesis. Some, though by no means all are
actually toxic, currently the is a bit of a crisis on the
California coast, hundreds of seals and otters are sick after
eating fish and shellfish poisoned by this stuff.


for a discussin of this and treatment with copper sulfate of a large
pond do a google in rec.ponds for John Rutz, Rod Farlee, and
cyanobacteria
I had a infestation of that last summer and Rod came up with the proper
dose for my pond it did not harm the plants or fish although it probly
set back the plants some

a little math would probly come up with the proper dose for another
sized pond
