Why Choose Our Grid Boards?

• Free Splicing System: Designed with secure interlocking tabs along the edges, allowing you to seamlessly snap multiple identical boards together. Easily create large, custom-sized partitions or massive floor grates for any size aquarium or commercial seafood vat.
• Dual-Purpose Application: Use them vertically with suction cup clips to divide a tank and protect fry/injured fish, or place them horizontally in your sump to elevate filter sponges, bio-rings, and ceramic media. This prevents dead spots and maximizes oxygen-rich water circulation.
• Two Precision Mesh Sizes: Choose the 30x15cm board with larger 1.5cm holes for high-flow filtration applications, or the 30x30cm board with smaller 1.0cm holes to safely contain smaller fish species and finer filtration media without them falling through.

⚠️ Crucial Purchase & Installation Guide: Please pay close attention to the sizing! Boards of different dimensions (30x15cm vs 30x30cm) feature different interlocking tab spacings and CANNOT be spliced together. Always purchase the exact same size boards for a single continuous grid project. The sturdy 0.65cm thick plastic material can be easily modified and cut with wire snips or a small saw to fit around PVC plumbing or irregular tank shapes.
