Tom,

If I read your post correctly, you are recommending that it is important to
have a fully functional biological filter with a healthy colony of
nitrifying bacteria in it as a sort of hedge against green water???? The
bacterial mass in the filter should be able to get any excess ammonium
BEFORE the algae can go ballistic. The higher plants would either have to
compete with the biofilter for ammonium or settle for using nitrate (which
of course, they can do), that the biofilter would produce. In some cases
this could require, in addition to the mechanical maintenance of the
biofilter (flow rates, thruput, etc.) that folks might have to add ammonium
to their tanks (in measured amounts of course, monitored by a good test
kit).

Either way, green water problems should be more manageable?
