Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 4L

CARBON PRODUCTION: All plants require a source of carbon, and Flourish Excel is a great and convenient source of bioavailable organic carbon.

IRON PRODUCTION: Flourish Excel also possesses iron reducing properties, thus promoting the ferrous state of iron (Fe+2), which is more easily utilized by plants than ferric iron (Fe+3).

PHOTOSYNTHESIS: Plants must produce longer chain carbon compounds (photosynthetic intermediates). By dosing with Flourish Excel you bypass the involvement of chain carbon compounds and introduce the already finished, structurally similar compounds.

TREATMENT: On initial use or after a major (> 40%) water change, use 1 capful of Flourish Excel (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. For smaller dosing please note that each cap thread is approximately 1 mL.

SAFETY: Flourish Excel is completely safe for fish, however, if you have Anacharis in an aquarium in which you are dosing Flourish Excel, then it is recommended to use it every other day rather than daily.
