I guess I should have posed the question a little better. Is it needed is
what I really want to know. Most of the plants are slow growing, but there
will be a lot of plants taking nutrients soley from the water column. Aside
from the K2SO4 will the fish produce enough of the other nutrients to keep
the slow growers happy? Or should I dose with a comercial fert on a weekly
