Any time you let any organic material decay within the system it will
release nutrients back into the system. An important part of algae
management is manual removal of as much algae and deteriorating plant
material as possible.
It seems to me that we've come a long way from my initial statement that it
was possible to maintain nitrogen poor water and still provide an adequate
amount of nitrogen to the plants via the substrate. I feel like we're
playing that "telephone" kids game!<g>
