0.8'' Aquarium Filter Material, 4.4lb Bio Blocks Material, Replacement Biological, for Aquarium,Fish Tank,Pond

The fish pond bio-ball filter is well-made, durable, and can effectively filter garbage in the water. When garbage accumulates in the bio-ball, it can be rinsed with clean water to remove stains.Made of brand-new materials, it will not cause secondary damage to the water quality. The sphere adopts a porous structure as a whole. The water flow constantly changes the direction of the water flow in the dense gaps, prolonging the water flow time, creating action time for the cultivation of nitrification garbage, and achieving a filtering effect.Specifications:Name: Fish tank nitrification small blockSpecifications: 2 litersSize: 2x2x2 cm/grainApplicable: small fish tank, can handle 25-50 liters of waterFunction: remove garbage in the waterScope of application: suitable for top filter, bottom filter and external filter of fish tankPackage includes:2 liter fish tank nitrification small block
