This document describes Nualgi, a patented nano-technology plant nutrient that promotes photosynthesis and rapid growth of diatom algae. It can be used to increase diatom algae growth in various water sources. Diatom algae absorb nutrients and carbon dioxide while producing oxygen through photosynthesis. They are consumed by zooplankton and fish, so they do not accumulate in water. Nualgi contains micronutrients like silica, iron and manganese that stimulate diatom algae growth. It has been successfully used to treat wastewater and increase dissolved oxygen in lakes and sewage treatment plants.
