Built around your tank. Made for the way you reef. Meet the PolypTop for Aqua One ReefSys 326, a made-to-order mesh-style lid created by The Polyp Pros. A neat PolypTop can transform the day-to-day experience of an Aqua One setup, adding a practical cover without closing off the view into your aquascape. A neatly finished open-mesh centre helps keep adventurous fish in the aquarium while preserving that airy, light-filled view.

The ReefSys 326 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 Aqua One 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 Aqua One product.
