Product description All-in-One Solution for Fish Isolation, Aquascaping & Filtration – Make Aquarium Maintenance Easier! Tired of fish fighting or low fry survival rates? This aquarium grid divider kit is designed for aquarists, featuring 3 grid panels (30x30cm/11.8x11.8 inch) + full installation accessories – no extra purchases needed, ready to solve multiple needs. Safe Material for Aquatic Life Made of high-purity PVC, rigorously tested for safety. It won’t release toxins in freshwater or saltwater, ensuring no impact on water pH. Fish, shrimp, and plants thrive in a healthy environment. The material is flexible, corrosion-resistant, and more durable than ordinary plastic boards. Flexible Installation for Any Tank Grid panels can be trimmed with scissors or wire cutters and spliced to custom sizes. 6 strong suction cups attach firmly to glass walls, 12 foot pegs prevent sliding on the tank bottom, and 10 cable ties reinforce structures – ideal for isolating sick fish, breeding zones, turtle basking platforms, or securing rocks/driftwood. More Than Isolation – Boost Filtration Efficiency As a bottom filter partition, the uniform grid gaps separate filter media (e.g., ceramic rings, bio-sponge), optimizing water circulation. This promotes nitrifying bacteria growth, rapidly decomposing fish waste and residue, reducing water changes, and keeping water clear and stable. Wide Applications for All Aquarists Perfect for home desktop tanks, office large aquariums, saltwater reef tanks, or freshwater aquascapes. Ideal for isolating breeding pairs, aggressive fish (e.g., cichlids, bettas), or DIY creative aquascaping – practical and aesthetic for both beginners and experts!
