FAQ: I'm using Seachem Flourite® as my only substrate, do still need Flourish Tabs™?

While Flourite® is a rich source of iron and some minerals such as manganese, it is primarily a porous substrate/gravel base for the planted aquarium. Flourish Tabs™, while not truly necessary for successful plant growth in a Flourite® substrate, does supply a broader and more easily utilized source of minerals than does Flourite® alone.
