Chaetogro Chaetomorpha and Refugium Fertilizer

Sorry, this item is out of stock

ChaetoGro helps establish water chemistry promoting long-term chaetomorpha health and growth, assisting the algae to efficiently control unwanted nutrients in the system, such as phosphate and nitrate.  This multi-nutrient is phosphate and nitrate free, containing such as iron, cobalt, molybdenum, and more for elements to help chaetomorpha function.


  • For all marine aquariums & ULNS systems
  • Shrimp & Invertebrate safe
  • Phosphate & Nitrate free
  • Provides 13 elements critical to long-term health, growth, and coloration of aquatic plants
  • Well-suited to ULNS aquariums and designed for nutrient control of phosphates and nitrates by chaetomorpha uptake
  • Formulated utilizing extensive research on aquatic algae nutrient requirements


Technical Background

Algae requires nutrition in order to survive and thrive; those nutrients needed allow algal biological functions and chemical reactions to properly process. Brightwell Aquatics ChaetoGro provides the proper substances in concentrations (found by researchers) to be necessary for long-term health. These elements, and some of the processes that they are involved in, are:

  • Potassium - Protein synthesis, water and charge balance, enzyme activation
  • Boron - Chlorophyll production, flowering, root growth, cell function
  • Carbon - Required for all organic compounds
  • Calcium - Cell wall stability and permeability, enzyme activation, cell response to stimuli
  • Chlorine - Water and charge balance, photosynthesis
  • Iron - Required for photosynthesis, component of enzymes utilized in redox reactions
  • Magnesium - Component of chlorophyll, enzyme activation
  • Manganese - Formation of amino acids, enzyme activation
  • Molybdenum and Cobalt - Required for nitrate reduction
  • Nickel - Enzyme activation, processing of nitrogenous material
  • Sulfur - Component of proteins and the coenzymes that are involved with nutrient utilization and growth
  • Zinc - Chlorophyll production, enzyme activation

Note: ChaetoGro does not contain phosphorus or nitrogen
