During the day algae take up carbon dioxide and release
oxygen into the water column through
photosynthesis. This can cause DO levels to increase. During
the night, algae take up oxygen and release carbon dioxide
into the water column.This
can cause DO levels to decrease. Algae, suspended below the
surface, cannot photosynthesize and, as a result, they
decompose. The decomposition process consumes dissolved
oxygen, and, as a result, DO levels in the water column can
decrease.
We recently received a telephone
call from a customer who, to say the least, was somewhat excited about
the clarity and performance of his aquarium. He had treated his system
with CB-FBM and needed to tell us about it. Part of the conversation went
like this - "You won't believe how clear the water is.
It looks like they
(evidently he is
referring to the fish) are
suspended in mid air..." On October 12, he
sent us the following images via email.
