Nualgi aqua is a Nano nutrient when added to water produces a bloom of diatoms starting almost immediately. The availability of diatoms triggers the growth of zooplankton. The watercolor changes to golden brown or light green. The growth of diatoms crashes out the blue-green algae which come out like green paint and has to be removed physically. The growth of diatoms is not measurable since they are immediately consumed by zooplankton. The growth of diatoms also produces plenty of Nanobubbles of pure oxygen underwater by photosynthesis. The zooplankton becomes food for fish and prawns. The oxygen produced underwater helps maintain good Dissolved Oxygen (D.O) in the water. The DO maintained by diatom photosynthesis is far superior to the use of mechanical aerators and far cheaper. The oxygen helps aerobic bacteria (Probiotics) clean up the fecal matter and uneaten food in the ponds thus helping have a good culture.
