Seachem Flourish Excel is a bioavailable liquid organic carbon source for planted aquariums.
It mimics photosynthetic intermediates, enabling aquatic plants to grow without CO₂ injection and also supports ferrous iron (Fe²⁺) availability, enhancing nutrient uptake.
Key Features:
Organic Carbon for Plants Provides plants with readily usable carbon compounds, bypassing traditional CO₂ uptake.
Iron-Reducing Action Promotes ferrous iron (Fe²⁺), which is more beneficial for plants than ferric iron (Fe³⁺).
CO₂ Alternative or Supplement Effective both as a CO₂ substitute and as a complement to injected CO₂ systems—with Excel alone delivering ~60–70% of the growth potential of CO₂.
Easy Dosing Protocol
Initial use / post–water change: 5 mL cap per 40 L (10 US gal)
Maintenance: 5 mL per 200 L (50 US gal) daily or every other day.
No pH Disturbance Does not significantly lower pH like CO₂ can; safe for tanks where stability is key.
