Diana also said to feed the fish plenty. Several times she mentioned to feed excessively.
Also, dirt provides micro not macro unless you get some anaerobic action in there. If you keep lightning low it will provide for many years. Otherwise, heavy root feeders will deplete the soil in several months.
Depending on the soil's composition there is a slight possibility for the soil to bind nutrients from decomposing organic matter.
