[APD] Excel = Barley/maple extract?



The press release "Are fish made of Maple leaves":
http://www.ecostudies.org/press/fish_maple_leaves.html
and the rave about simple sugars as DOC-source for aquatic
plants and algae killer (Seachem Excel) made me think.

Maple leaves releasing carbohydrates. Barley straw 
releasing carbohydrates/DOC and "killing algae". 
Seachem Excel.

Barley propaganda:
http://www.barleyworld.org/barleystraw/straw.pdf

"No direct effect of straw on aquatic vascular plants has 
been found in either laboratory or field experiments. 
However, in several trials where straw has successfully 
controlled algae, there has been a noticeable increase in 
the growth of submerged vascular plants."

Good source of carbon = Happy plants = Less algae.

"If snake oil x was such a good algae killer, company y 
would have made it comercially available long time ago!"... 

Hmmmm...
