Dosing Planted Aquarium Nutrients

Freshwater Planted Aquarium Suggested Dosing for a Planted Aquarium*
It won't always be necessary to dose your aquarium with each of the products in the Flourish line, but as an example, we have developed one possible dosing regimen using all of our plant products. This is by no means the only way to dose your aquarium; it is merely a suggestion. Your dosing regimen will depend greatly on a variety of factors, including lighting, initial water quality, how heavily stocked your aquarium is, substrate selection, and types of plants; so don't be surprised if getting the results you want takes a little experimentation.
