Microcyst are considered as harmful algae which influence the ecosystem as well as food chain of the pond and affects the overall culture. This microcysts are releasing much of toxic substances including CO2and ammonia which leads to many pathogenic infections in the culture pond. Thus, BIGREEN TECHNOLOGIES have developed RA CONTROLLER with a nano-mineral composite which controls the microcysts in the pond and helps to enhance the oxygen level and eradicating the ammonia, thus controlling the microcysts in the aqua ponds.
