This hypothesis has been proferred several times in various quarters. What's
been lacking is the demonstration. But that's the case with most of what
goes on in the hobby.

ambient O2, but not low O2. Adding lots of dead plant matter can cause the
O2 to go lower rapidly. I did not test this parameter, but will in the
future test. 

That will be interesting. If low O2 is correlated to increased algae 
growth, the corollary will also be true. That would offer a good 
explanation of why strongly growing plants discourage algae ... 
super-saturation of O2. Same effect achieved with peroxide.
