Pro Bio S is designed to be used with the Probiotic System. Its main purpose is to help stimulate the growth of bacterioplankton. The culture medium will help with the overall reduction of nitrate and phosphates while allowing your corals to consume the bacterioplankton which is one of their main nutrient sources. Recommended for smaller aquariums, where it is not possible to install filters with polymers.
