Your reef deserves a top that complements the view. Meet the PolypTop for Waterbox Peninsula 4820, a made-to-order mesh-style lid created by The Polyp Pros. Waterbox owners love an unobstructed display, and this PolypTop helps keep the look tidy while making space for the equipment that sits around the rim. Its open-mesh centre helps discourage jumping fish without hiding the colours and movement of your reef.

The peninsula format rewards careful placement: tell us which ends are accessible and where the equipment approaches the tank. Our goal is a smart, restrained look that complements the aquarium rather than competing with it.

Your lid, your layout. Tailor the top to your setup before we manufacture: light mount cutouts for brackets, cable/wire cutouts for equipment leads, and an optional frozen-food feeder hole for convenient feeding. Choose Yes or No for each option. If you need cutouts, use the Additional Cutout Instructions comments box to describe the type of cutout, quantity, approximate dimensions and exact positions (for example, a rear-left light bracket cutout, two rear cable openings or a front feeding hole). Leave the comments box blank if no cutouts are required. A feeder or feeding cup is not included.

Fit check before manufacture: Please provide the exact Waterbox model and generation, measurements of the tank rim and a photograph taken from above. We will confirm your layout and cutout positions before production. This listing is for the PolypTop lid only; aquarium, lighting, mounts and other equipment are not included. Tank brand and model names identify compatibility only; this is an independent The Polyp Pros accessory, not an original Waterbox product.
