A cleaner finish for the aquarium you love. Meet the PolypTop for Fluval Flex 57, a made-to-order mesh-style lid created by The Polyp Pros. Small aquariums have big personalities! Keep the profile smart and the aquascape visible with a PolypTop planned around your Fluval setup. Its open-mesh centre helps discourage jumping fish without hiding the colours and movement of your reef.
The Flex 57 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. 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. In the required Tank model, rim size and cutout instructions text box, enter your exact aquarium model, generation and rim measurements (mm). If you select any cutouts, also specify their type, quantity, approximate dimensions and exact locations (for example, a rear-left light bracket cutout, two rear cable openings or a front feeding hole). If no cutouts are needed, enter 'no cutouts'. A feeder or feeding cup is not included.
Fit check before manufacture: Please provide the exact Fluval 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 Fluval product.
