Plastic Aquarium Drain Strainer & Fish Guard

Secure your plumbing and protect your tank inhabitants with our versatile Plastic Drain Mesh Covers from Atradesen.com. Specifically designed for side filters, bottom drains, and overflow boxes, this essential guard prevents small fish, shrimp, and large debris from being sucked into your filtration system.

🌟 Ultimate DIY Flexibility

• Anti-Clog Protection: Keeps your pumps running smoothly by blocking foreign objects and decaying leaves from entering the main plumbing lines.
• Snap-In Installation: The medium and large sizes feature built-in rear prongs (clips). If your pipe's inner diameter matches, simply push it in for a secure friction fit!
• Ultimate DIY Surface Mount: Pipe diameter doesn't perfectly match? No problem! Simply break or clip off the rear prongs with pliers, and use aquarium-safe silicone to glue the flat mesh directly over any drain hole!

⚠️ Sizing & Fitment Guide (Crucial!)

Please review the Atradesen.com dimensions below. The "I.D." refers to the size of the rear insertion part, and "O.D." is the total outer lip width.

• Small Size (Round Holes): O.D. 30mm | I.D. 25mm (Insert fits into a ~25mm hole).
• Medium Size (Square Mesh): O.D. 45mm | I.D. 40mm (Insert prongs fit into a ~40mm hole).
• Large Size (Square Mesh): O.D. 65mm | I.D. 60mm (Insert prongs fit into a ~60mm hole).
• 💡 Pro Tip: When in doubt, buy a slightly larger size, snap off the back clips, and silicone it flat over your drain!
