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.

Good luck
