Seachem Flourish Excel 250 mL – Planted Aquarium Carbon Supplement

Seachem Flourish Excel 250 mL is a liquid carbon supplement for freshwater planted aquariums. It is commonly used in low-tech planted tanks, community aquariums with live plants, and planted setups where aquarists want to supplement carbon without using a pressurized CO2 system.

Planted Tank Tips

  • Follow the Seachem label for dosage and frequency
  • Dose consistently rather than making large sudden changes
  • Balance lighting, nutrients, and carbon supplementation

  • Use caution in shrimp tanks and sensitive planted setups
  • Do not use Excel as a replacement for all planted tank fertilizers
  • Trim unhealthy plant growth and remove decaying leaves as needed

Important Planted Aquarium Note

Plant growth depends on more than carbon alone. Lighting, substrate, fertilizer, CO2 use, plant selection, water parameters, water changes, and maintenance routine all affect plant growth and algae control.

Flourish Excel may be used as part of a planted tank routine, but it does not replace complete plant nutrition. Many aquariums may also need macro and micronutrient supplements depending on plant type, lighting level, and growth rate.
