LINLAN 8 Pieces 5.9×11.8in (15X30cm) Aquarium Grid Plastic, Fish Tank Divider, Egg Crate for DIY Filtration and Bottom Protection in Aquascaping (Black-No Accessories)

The aquarium grid divider is a versatile tool commonly used in aquatics. Its interlocking and cuttable features, combined with its safe plastic material, make it suitable for a wide range of aquatic applications. 
1. As an Aquarium Divider: By using suction cup holders, the plastic grid divider can be securely fixed to the glass walls of the aquarium, effectively creating separate sections. This is ideal for mixed species tanks or for the emergency isolation of sick fish.
Note: The grid size is 1 cm, which means small fish may pass through the divider, failing to achieve complete separation. Additionally, due to the strength of the suction cups and the grid connections, it is not suitable for isolating large fish. 
2. As a Tank Lid or Fish Jump Prevention Measure: When used with aquarium wall mounts, the plastic grid divider can be fixed above the tank to prevent fish from jumping out and to protect the aquatic life from pets such as cats.
Note: Choose the correct holders to achieve high fixing strength. Different holders may vary in ease of opening and closing. Pay attention to the size and type of fish. Very large or very small fish may not be suitable. Use large, uncut grid pieces to minimize the number of joints, which will maintain better connection strength. Too many joints may cause the middle sections to sag. 
3. As a Bottom Protector During Aquascaping: In extreme cases, we may use large stones or uniquely shaped driftwood for aquascaping, which could place a strain on the bottom of the tank. Using the grid divider as a base layer can effectively protect the tank bottom, preventing scratches and distributing weight evenly. The plastic material is very safe, and we highly recommend this method. 
4. As a Filter Material Separator: Standard filtration equipment usually comes with its own compartments, but the grid divider provides another option for DIY enthusiasts and professional aquarists. To maintain clean water, we often use multiple types of filter media. The separator can keep different media apart, making cleaning and reuse easier. We highly recommend this approach. 
5. Unleash Your Imagination: The grid divider has many potential uses, whether in aquatics or in other areas like reptile habitats. It can be used to create turtle basking platforms, pump protection compartments, and initial setups for external tank landscapes. 
Important Notes: Handle with care and wear gloves, as the edges may be sharp. Packaging and measurements are done manually, so there may be a 1-3 mm deviation. If you have any questions, please contact us. We are committed to providing satisfactory service and solutions.
