Premium Acrylic Aquarium Overflow Box Comb (10-30cm) | Fish Guard Barrier Weir with Suction Cups | Reef Tank Plumbing

Premium Acrylic Aquarium Overflow Box Comb

Protect your valuable livestock and maintain a whisper-quiet filtration system with our Premium Acrylic Overflow Combs from Atradesen.com. Expertly designed to sit at the edge of your internal overflow box or weir, this barrier allows water to flow freely into your sump while physically blocking fish, snails, and large debris from taking a deadly plunge.

🌟 Ultimate Livestock Protection

• Precision 3mm Gap: The meticulously spaced 3mm slots ensure massive water turnover (30mm gap height) while keeping 99% of fish and cleanup crew safely inside the main display tank.
• Premium Cast Acrylic: Crafted from high-grade, reef-safe acrylic that won't warp, yellow, or leach chemicals. Available in Crystal Clear (to blend in with glass) or High-Gloss Black (to elegantly hide dirty overflow plumbing).
• Versatile Installation Options: Choose the "Without Suction Cup" model for permanent installation using aquarium-safe silicone/glue, or select the "With Suction Cup" model (features pre-drilled holes and includes cups) for a quick, adjustable, and easily removable setup.
