Just to point out...Flourish root tabs is not the same as dry ferts. By dry ferts they mean Plantex CSM+B most likely. It is a powder that you add to distilled water then add as a liquid in most cases. It is basically Flourish minus some trace elements at about 1/4 the cost.

Flourish Excel is a Carbon additive to take the place of CO2. It is also known to kill/control some types of algae.
