Doug, sometimes this newsgroup needs a healthy dose of the obvious. <g>
I, for one, had no idea that phosphate was relatively immobile in soil.
To chew up more bandwidth, I think we all yearn for a connection with
the natural world and aquariums are one way of doing that. Hiking is
another. When we make our aquariums as "natural" as possible for our
goals, we are happy. And what else is a hobby for?
Thank you.
