[APD] Fw: Excel = Barley/Maple extract?

That one is interesting. It says that DOC produced by the decomposition of
barley in the presence of both oxygen and light causes the formation of
oxygen atoms that then form hydrogen peroxide in the water. The authors
postulate that the peroxide kills algae, based on studies of peroxide and
algae. They also indicate that when algae is suppressed then plant growth is
enhanced, *not* that when plant growth is enhanced then algae is suppressed.

Exactly, perhaps they should look at it from our perspective.

Not the peroxide recurring nonsense as Hieber points out, but the fact
that in shallow waters, like ponds, the raise in DOC gives the plants
the advantage and the algae decline?
