MicroBacter Purple M by Brightwell Aquatics introduces a powerful, shelf-stable blend of purple non-sulfur (PNSB) bacteria to your reef system. These live photosynthetic microbes thrive in both oxygen-rich and low-oxygen environments, making them effective in deep sand beds, refugiums, reactors, and even your main display.
By naturally breaking down excess nutrients and organic waste, Purple M helps maintain a cleaner, more balanced system while serving as a nutritious food source for corals, sponges, and other filter-feeding inverts. Use alongside MicroBacter7 and MicroBacter Clean for even greater nutrient control and microbial diversity.
