Laguna BioMax Media 12.3 oz. (MPN PT560)

Thanks to its unique ceramic structure, Bio-Max promotes, protects and encourages beneficial bacteria in pond water, resulting in a clean, clear pond. Bio-Max has a large surface area and number of pores perfectly sized to allow beneficial bacterial colonies to thrive, creating a bacterial sanctuary that maintains a biological balance in pond water. Beneficial bacteria living in the micro-tunnels and micro-cavities naturally eliminate ammonia and nitrite, which are toxic compounds that originate from pond inhabitants, decomposing organic matter, and runoff from surrounding terrain.
