Rinhoo 16mm Black Aquarium Bio Ball Biochemical Filter Sponge Fish Pond Waterfall Fountain Filter

Description The biosphere is a hollow sphere made of plastic material. It has a large surface area and can attach a large amount of nitrifying bacteria. There is no resistance when the water flows through, and the hollow structure divides the water into a thin stream and crushes the large pieces of dirt, and the filtering effect is excellent. Because the biosphere is light in weight and easy to carry, it can be used not only in biochemical filtration systems in seawater, but also in biochemical filtration systems in freshwater. The principle of biochemical ball is to let the water flow through the space which is distributed in the internal part, to prolong the flow of water, and to add the nitrifying bacteria attached to the multi-column structure to achieve the effect of biochemical filtration. The filter of each aquarium is limited, and the filtering space for placing the biochemical ball is not too large, but the function of the biochemical ball is used to make up for the lack of filtering space. Specification: Color: black. Material: PVC. Size: 16mm. Note: Because of the resolution of the screen, the color may be a little different. There may be some errors in size due to the way of measurement. Package included: Type 1 10 * bio balls. Type 1 50 * bio balls.
