Safe materials: Nontoxic, aquariumsafe construction to protect fish and plants over time, supporting a balanced, sustainable aquatic ecosystem. Multifunction design: Combines hydroponic planting support, fishzone division, and root stabilization to help you organize plants and separate areas as needed. Spaceefficient: Fits both square and round tanks; grips the tank walls securely to maximize open water space and minimize clutter. Enhanced water flow: Side slots promote circulation and bottom holes allow throughflow, helping keep the water clean and delivering nutrients to plant roots. Broad compatibility: Suitable for freshwater setups, glass or acrylic tanks, and a range of common plant types and sizes. Practical use scenarios: 1) In a small community tank, use as a plant anchor to prevent uprooting and to create a subtle plant zone that reduces fish interaction with roots. 2) In a round nano tank, place among plants to stabilize root areas without crowding the center, preserving viewing space. 3) In a flow tank, leverages throughflow design to prevent stagnation and improve nutrient delivery to rooted plants. Key attributes: durable, aquariumsafe material; adaptable to different tank shapes; supports plant growth while maintaining fish separation; easy installation and maintenance.
