The D&D Jumpguard Aquarium Cover is a lightweight, sleek, and highly effective solution designed to prevent fish from jumping out of rimless aquariums. Unlike bulky glass tops or heavy plastic lids, the Jumpguard utilizes a low-profile aluminum frame and a specialized transparent mesh that allows for maximum light penetration and gas exchange. Its modular design makes it fully customizable, allowing aquarists to create a perfect fit around light mounts, cables, and overflow boxes, ensuring total security without compromising the clean aesthetic of a modern reef or planted tank.
The Jumpguard is engineered to protect your livestock while maintaining the high-performance environment required for corals and plants.
Minimal Light Interference: The ultra-fine transparent mesh has a negligible impact on PAR levels, ensuring your high-intensity lighting reaches your corals without distortion.
Optimized Gas Exchange: The open-mesh design prevents the buildup of heat and $CO_2$ that typically occurs with solid glass covers, helping to maintain a stable $pH$ level.
Customizable Frame System: The powder-coated aluminum extrusions can be easily cut to size with a standard hacksaw to fit any aquarium dimensions.
Discreet Aesthetics: Finished in a sleek black or silver, the thin profile sits on the inner lip of the glass, preserving the "rimless" look of your tank.
Varying Sizes: Available in multiple kit sizes ranging from 60 cm to 180 cm to accommodate everything from nano tanks to large-scale reef displays.
Is the Jumpguard easy to assemble?
Yes. The kit includes all necessary corner pieces, aluminum rails, mesh, and a spline roller. It is designed to be a DIY project that can be completed in about 30–45 minutes with basic household tools.
Can I fit it around my light brackets?
Absolutely. D&D offers optional Multi-Cutout Kits (sold separately) that allow you to create neat, professional offsets for lighting mounts, filter pipes, or cables.
Will the mesh salt-creep or block light over time?
The mesh is made of a durable, salt-resistant monofilament. While it is very resistant to buildup, we recommend a quick rinse with fresh water every few months to ensure maximum light transparency.
Does it fit tanks with non-standard glass thickness?
The Jumpguard is designed to sit on top of the glass or on the internal rim. It is compatible with almost all glass thicknesses ranging from 6 mm to 20 mm+.
D&D Jumpguard Multi-Cutout Kit: The essential add-on for creating professional gaps for arm-mounted lights or large overflow boxes.
D&D Jumpguard Feeding Portal: A neat, circular hatch that can be installed into the mesh to allow for easy feeding without removing the entire cover.
D&D Jumpguard Flexi-Soss Corners: Specialized corners for tanks with rounded front edges or unique geometric shapes.
