Customizable DIY Aquarium Net Cover

Keep your finny friends safe inside your tank with a customizable Red Sea Aquarium Net Cover.

With a sleek profile and minimalist hangers the Red Sea Net Cover blends in seamlessly even on ultra-clear, rimless, open-top aquariums.

The extra strong aluminum frame and purpose designed components allow the extra thin transparent net cover to be customized to accommodate rim-mounted equipment such as lighting arms, auto-feeders and overflow boxes.

Check out our how-to video that shows exactly how to assemble Red Sea’s fish saver, step-by-step. Keep in mind that this is a Do-it-Yourself cover, and while it offers versatility and customizability at a fraction of the cost of custom-built covers, it does require proper DIY skills including planning, taking exact measurements and cutting aluminum profiles. So if you aren’t a DIY project kind of hobbyist, you can always ask your local dealer or a handy friend to help.

The moment you touch it, you know it’s not going to have any flex to it

Ryan would choose a Red Sea DIY Net Cover over BRS's very own DIY Screen Net Top cover!

Designed specifically for rimless tanks the Red Sea cover also works well with braced tanks such as the MAX^® S-series.
