Premium Modular Undergravel Filter Plate

Build the ultimate biological filtration system or create a perfect false bottom for your aquascape with our Modular Undergravel Filter Plates from Atradesen.com. Highly recommended by professional shrimp breeders, these interlocking grids are manufactured from 100% food-grade plastic, ensuring zero chemical leaching into your pristine water parameters.

🌟 Advanced Engineering & DIY Friendly

• Optimum 3x3mm Micro-Mesh: The precision 3mm grid allows unrestricted water flow while preventing expensive aquasoil, gravel, or baby shrimp from falling through.
• Elevated 2.7cm Base: The raised leg supports create a spacious 2.7cm (approx 1 inch) void under the substrate, maximizing oxygenation for beneficial bacteria and making it easy to observe detritus buildup.
• Easy Custom Cutting: Have a uniquely shaped tank? No problem! The food-grade plastic is rigid enough to support heavy rocks but can be easily trimmed to the exact millimeter using standard heavy-duty scissors or a utility knife.

⚠️ Buying Calculator: How Many Plates Do You Need?

Each plate measures 14.5cm x 14.5cm. Use this simple Atradesen.com formula to calculate your required quantity:

• Formula: (Tank Length ÷ 14.5) × (Tank Width ÷ 14.5) = Total Plates Needed.
• Example for a 90cm x 45cm tank:
  1. Length: 90 ÷ 14.5 = 6.2
  2. Width: 45 ÷ 14.5 = 3.1
  3. Total: 6.2 × 3.1 = 19.22
  👉 You would need to purchase 20 plates to fully cover the bottom!
• Connection Tip: If running an uplift tube, purchase mostly "Flat Plates" and just 1 or 2 "Connector Plates" to attach your vertical pipes.
