If it is humic acids that are the magic bullet, would not peat moss work just as well as barley straw?  Many 
people have had good luck using peat in the substrate or in filters.  

We used to use Duplgan water conditioner when it was available. It resembled, in 
color at least, peat water. Perhaps it contained some humic acid and was thus 
beneficial to algae prevention (Dupla never stated it was good for that; it was 
just a water conditioner with "natural" things).  

Oh, and if barley is the magic bullet, how about using a dosing pump to inject 
small amounts of Budweiser?  Or Michelob for the high tech people. Or is Coors 
the magic bullet?  No, that's Coors Light and the Silver Bullet.  Nevermind :-) 

Just kidding. Please don't inject beer into your tank.
