Or put another way, how much might have to be added? I've used some of
the prepackaged mineral/fertilizer liquids to no avail. I put something
like a cup of iron in my 1200 gallon pond and the hyacinth still aren't
as green as when I got them.

Is there a way to test for these trace minerals? Right now the pond is clear
with lots of plants and fish but the plants just don't seem to be doing as well
as they could. I have Pickeral, Lillies, iris, and hyacinth. Also, where could
I get some of the Tetra Pond fertilizer? The selection of pond stores in New
Mexico is pretty sorry and they overcharge.
