Cichlidiot - I have read a number of times that Anacharis is not truly an
oxygenating plant. That there is little net yield in oxygen due to
respiration and should really only be put in a pond for its value of using
up excess nutrients in the water. Do you believe there is greater benefit
in more confined aquariums(I'm setting up two)? Of course, this could be
the ol ask 6 people and you'll get five different answers since some sites
are so specific about having x bundles per x square ft of pond surface.
