Seachem Flourish Excel - Bioavailable Organic Carbon for Aquatic Plants (250 ml)

About this item

• 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.
• CARBON PRODUCTION: All plants require a source of carbon, and Flourish Excel is a great and convenient source of bioavailable organic carbon.
• 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.
• 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.
• IRON PRODUCTION: Flourish Excel is capable of reducing iron, favoring the ferrous state (Fe+2) over ferric iron (Fe+3), making it more plant-accessible.
