Then why do some people speak of 'crystal clear' water in their ponds? -
question not an arguement.

Because it is not in balance. It is forced to be clear by filtering,
not by natural balance. My pond is in natural balance with no filtering
at all. The water is extremely clear, but has a slight yellowing-brown
cast. It is 3' to 4' deep.

They may not be balanced "naturally" but they are still balanced. The
filters add the additional surface area for the higher fish load, to make
them so. There is no "forcing" because a pond that is filtered isn't always
balanced, clear or quality-wise. ~ jan
