About Fluval External Power Filter Pre-Filter Media
Fluval Pre-Filter consists of inert, solid ceramic rings used to trap large and medium solid particles before they clog the finer sieves of the modules above. The diversified water flow allows the establishment of biological activity on the surface of these rings, adding to the overall biological action on ammonia and nitrite. Fluval first broke onto the aquatic scene in 1975 by introducing the world's first 3-stage filter with synchronous motor technology a landmark breakthrough that is still applied in the. s- media capacity 3.2 Liters 4.6liters, 6.6liter, 9.6liter, and 11.5liter batteries. Fluval carbon is capable of adsorbing most liquified impurities and dyes present in aquarium water. It does not contain phosphates and will not change the pH of the aquarium. Fluval Foam Filter Blocks provide mechanical straining of particulate waste. They prevent prematurely clogging other filter media in the module stack. The ion-exchange media is prevented premature clogging of finer filters and extends their life. Fluval bio-foam increases surface area for the growth of helpful nitrifying bacteria.
