It also appears to work with Algae

Muddy water caused by suspended clay particles can sometimes be corrected
by spreading broken bales of high quality hay or barley straw in the water
around the shoreline. Acids formed during plant decay can cause clay
particles to settle. Approximately two bales of hay per surface acre
should clear the water. Do not use too many bales and do not use uncured
or fresh cut vegetation. Either mistake may cause a fish kill. To
determine if this method may work, add twotablespoons of vinegar to your
water sample. If it clears overnight, use of bales will probably work.

Has anybody tried Phoslock for getting rid of green algae in
fishponds?

Their web page claims it is the best thing since sliced bread for
doing that, but I would like an independent evaluation before sending
them my dough.
