Brightwell Aquatics FlorinAxis Carbon Source & Krebs Cycle Stimulator, 125 ml Brightwell Aquatics FlorinAxis Carbon Source, 125 ml


  • A concentrated source of bioavailable carbon, Krebs cycle intermediates, humic and amino acids, and naturally-occurring phytohormones
  • May be used as a primary or supplementary source of carbon (compatible with CO2 supplementation)
  • Provides key components of the Krebs cycle, the series of biochemical reactions that are ultimately responsible for converting complex organic molecules into energy in all aerobic organisms; benefits are more efficient metabolism of foods and available nutrients for fishes and plants alike, as well as enhanced decomposition of latent organic material
  • Provides naturally-derived sources of humic substances, which aid plants in the uptake of important nutrients such as iron, calcium, magnesium, etc., and can even increase the availability of these substances in the aquarium environment
  • Formulated utilizing extensive research on aquatic plant nutrient requirements and Molecular Biology

Brightwell Aquatics FlorinMulti Multi-Nutrient Fertilizer, 125 ml Brightwell Aquatics FlorinMulti Multi-Nutrient Fertilizer, 125 ml


  • Provides 14 elements critical to long-term health, growth, and coloration of aquatic plants
  • Elemental ratio reflects current understanding of general requirements for unrestricted growth of tropical aquatic plants
  • May be used to establish beneficial water parameters in new aquaria, to replenish depleted elemental concentrations in aquaria, to replenish depleted elemental concentrations in aquaria that rarely receive a water change, and to re-establish concentrations in aquaria following large water changes
  • Well-suited to the planted aquarium hobbyist seeking one simple solution to use for the majority of plant husbandry requirements (e.g. aside from instances when specific water parameters require adjustment).
  • Also provides 0.001% iodine to enable crustaceans (such as shrimp) to molt and grow
