Benefits The benefits of Seachem Flourish Excel are: Natural organic carbon Ensures optimal photosynthesis in plants Restores aquatic plants to healthy state Ensures a beautiful planted aquarium Non-toxic, safe for plants CO2 for Planted Tanks The reason plants need CO2 (carbon dioxide) is to produce longer chain carbon compounds also known as photosynthetic intermediates. Photosynthetic intermediates includes compounds such as ribulose 1,5-bisphosphate, and 2-carboxy-3-keto-D-arabinitol 1,5 bisphosphate. Although the names are complicated, the structures are quite simple (5 carbon chains). Seachem Flourish Excel does not contain these specific compounds per se, but one that is quite similar. By dosing with Seachem Flourish Excel, you bypass the involvement of CO2 and introduce the already finished, structurally similar compounds. It is in its structural similarity that Seachem Flourish Excel is able to be utilised in the carbon chain building process of photosynthesis. Simple chemical or enzymatic steps can easily convert it to any one to any one of the above named compounds (or a variety of others). How to Use On initial use or after a major (> 40%) water change, use 1 capful (5 mL) for every 40 L (10 US gallons). Thereafter use 1 capful for every 200 L (50 US gallons) daily or every other day.
