The experience of aquatic gardeners seems to be diametrically
opposite. The plant bulbs when used over aquaria promote algae
growth much more that a full-spectrum bulb.
In a healthy planted tank algae is not a problem because the
vascular plants outcompete the algae.
Martin, I don't know the mechanism by which carbon takes out CO2. I would
venture to say that it is by some sort of molecular sieving or by a
polarity issue.
We might be talking about different algaes. I was referring mostly to
cyanobacteria.
The wonderful thing about aquariology is that everyone has a different way
of doing the same thing!
