Zhixan Plastic Egg Crate Set, 30x30cm Black Fish Tank Divider (113) for DIY Filtration, Bottom Protection, Aquascaping

【High-Density 1x1cm Grid Design】 Each panel measures 30x30cm / 11.8x11.8 inches with ultra-fine 1x1cm / 0.39x0.39 inch holes, denser than standard egg crate grids. The high-density aquarium grid plastic effectively prevents small fish, shrimp, and fry from passing through, while providing excellent support for filtration media and gravel. Safe for both freshwater and saltwater tanks. 【Complete 9-Piece Set with All Accessories】 This plastic egg crate set includes 9 panels, 18 black brackets, 36 adjustable support feet, and 50 self-locking nylon zip ties. Unlike other sets that only offer 6 or 8 pieces with fewer brackets, our large fish tank divider kit gives you full coverage and stable installation. The black PVC aquarium divider can be easily connected and customized to fit any tank size. 【Versatile Fish Tank Divider & Separator】 Use as aquarium divider to separate aggressive fish, create breeding zones, or isolate sick fish for quarantine. The fish tank separator also works as an anti-jump aquarium lid to prevent fish from jumping out. The egg crate design allows water flow while keeping fish separated, solving the common problem of fish fighting and stress in community tanks. 【Ideal Under Gravel Filter Support & Aquascaping Tool】 Place under gravel to create an under gravel filter aquarium divider tank system, optimizing water circulation and promoting beneficial bacteria growth. Also perfect as a crate divider for DIY filtration layers, bottom protection to prevent glass cracks from rocks, and foundation for aquascaping layouts. The support feet can be adjusted to create different heights for customized water flow. 【Multiple Applications Beyond Fish Tanks】 This plastic grid is not just a fish tank divider with suction cups alternative — use it as a turtle basking platform, shrimp breeding cage, coral frag rack, plant rooting grid, or reptile enclosure ventilation panel. The DIY-friendly material can be cut to any shape with scissors. Dimensions per piece: 30x30cm / 11.8x11.8 inches, hole size: 1x1cm / 0.39x0.39 inches.
