Thanks, everybody. That is interesting about the walstead method. My substrate consists of a 1" layer of cheap organic potting soil, covered with a thin layer of bentonite cat litter, covered with about 1 1/2" of gravel. Perhaps I have a walstead aquarium going without even realizing it. I wonder if I even need to add the flourish...it would be nice to get some cabomba going again.
