Beautiful display, practical details, no fuss. Meet the PolypTop for D-D 900 Pro, a made-to-order mesh-style lid created by The Polyp Pros. Give your D-D display a clean, intentional finish while keeping useful access around the lighting and the rest of your reef equipment. Its open-mesh centre helps discourage jumping fish without hiding the colours and movement of your reef.

The 900 Pro is the starting point for the design; send the specific generation and equipment layout so we can plan your lid properly. Our goal is a smart, restrained look that complements the aquarium rather than competing with it.

Your lid, your layout. Choose the finishing details to suit your equipment: 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 D-D 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 D-D product.
