Ideal for use in refugiums and algae reactors, this American-made solution ensures vibrant, thriving marine ecosystems. ## Description Nutrients are substances required by algae for survival; they are collectively involved in all aspects of the biological and chemical reactions that allow algae to function properly. Brightwell Aquatics ChaetoGro provides these 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. ChaetoGro does not contain phosphorus or nitrogen. Review: Algae nutrient supplement - This stuff is really good, not only for chaeto, but for fertilizing all macroalgae. Review: Excellent tool for a refugium or algae reactor. - I put this on an auto doser for daily dispensing. I dose 2ml per day. Since it's addition to my reef aquarium it has certainly boosted the growth of the chaeto in my algae reactor and in turn lowered my nutrient levels. ## Features - MULTI-NUTRIENT SUPPLEMENT – This multi-nutrient supplement for chaeto growth supplies essential nutrients necessary for the health and growth of chaetomorpha algae.
