50 Packs Filter Brushes Aquarium Brushes Set for Koi Pond Water Garden Outdoor Pond Skimmers Brush Filter Cleaning Brush 12 Inch by 4.7 Inch (Green)

Simply place the NinjaSieve vortex brush in the water flow, and it will quickly capture large particles of debris and adsorb suspended solids in the water. You can place multiple brushes above the vortex inlet or below the outlet to form a barrier, forcing the water flow to pass through the brush bodies. This physically intercepts all unsettled impurity particles. The more vortex brushes you install, the more impurity particles are collected, and the filtration surface area increases accordingly. The recommended fill quantity is 8~10 per square foot. It can be used as a further enhancement of pre-physical filtration when there is sufficient space in the filtration system and there is already a good pre-physical filtration function. According to the design of the filtration system can also be added or subtracted from the number, generally speaking, the higher the density of the filtering brushes, the better the filtration effect.
