I've looked into Seachem Flourish products. I see Flourish, Flourish Excel,
Flourish Trace etc...besides the obvious Flourish Iron, Potassium,
Phosphorus and Nitrogen, which one am I supposed to use?

Flourish: What the group calls "trace"
Flourish Trace: Even tracier traces.
Flourish Excel: Liquid carbon source for folks without CO2.

Flourish Potassium, Iron, Phosphorus, Nitrogen need no explanation
