Bioavailable organic carbon source: Promotes faster and healthier plant growth in freshwater aquariums
CO2 alternative: Enables plant fertilization without the need for CO2 injection, ideal for low-tech or non-injected setups
Algae control: Helps suppress nuisance algae, particularly black beard algae, by limiting carbon sources
Easy dosing: Simple to measure and apply for optimal results
Safe for fish and invertebrates: Does not alter water parameters and is non-toxic to aquatic life
Summarized by Shop
Flourish Excel™ is a source of bioavailable organic carbon. All plants require a source of carbon. This is typically obtained from CO, but, may also be derived from simple organic compounds (such as photosynthetic intermediates). The use of either CO injection or Flourish Excel™ does not necessarily negate the use of the other. Because
