Seachem Flourish Excel is a source of bioavailable organic carbon that all plants require. This is typically obtained from CO2, but may also be derived from simple organic compounds such as photosynthetic intermediates. Because the processes of producing photosynthetic intermediates and building onto them occur simultaneously, one can derive a substantial benefit with the use of Flourish Excel either alone or in conjunction with CO2. Seachem Flourish Excel also has iron reducing properties which promote the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).
