Polarization of light refers to the process by which the oscillations of the electric field vector within an electromagnetic wave become restricted to a single plane. The plane of polarization is determined by the direction of propagation and the orientation of the electric-field oscillations. #physics_theoriess #physicsfacts #physicsclass | Physics Theories

Bio-filters are a simple and efficient tool to remove ammonia and nitrites produced in fish waste from system water. At Pentair AES, we carry a wide range of biomedia suitable for many different types of filters, including bio barrels, bio-filter media pads, filter foam, and more. Biological filter media like bio-barrels work well in bag filters and have a very long lifespan. If you use a bioreactor, Sweetwater SWX Bio-Media is specifically designed for use in MBBR systems, offering abundant sur
