Well, well... the plot thickens... a Barley Straw reactor form Dupla no
less! Let's not stop experimenting though, my guess is such a Dupla
product will cost big buck$ ! Don't leave us hanging James, give us a link!

That seems to make perfect sense to me. H2O2 is light sensitive, that's
why peroxide is mostly sold in opaque plastic. If you follow the
reasoning, then its not light that makes Barley straw work, but oxygen.
Pure speculation here, but could pond straw in English ponds work b/c the
oxygen is greatest AT THE SURFACE of the pond allowing the Rxn w/ the straw
& production of peroxides? Can it be that this fact is misinterpreted as
the straw needing light to activate?
