Steve, I have seen a reference at
http://www.execpc.com/~aqsys/barley.html of a synopsis report of
Dr. Jonathan Newman, Centre of Aquatic Plant Mangement, England
which seems to provide some of the technoids behind this method
of algae control.
I note that the article indicates that the effective life of the barley
straw begins after it begins rotting in an oxygenated environment and
gradually ends approximately 6mths later. This would suggest perhaps
half the straw should be rotated every 3 mths so at least half the
contents in the canister is still effective.
