Free Shipping available on Ultum Nature Systems (UNS) 90L Long 21 Gallon Lid in the Continental USA
Kraken Reef lids are designed with your tank inhabitant's safety in mind while keeping your aquarium's stunning aesthetics. Our polycarbonate lid frame is proudly machined in the USA by Kraken Reef using a state of the art CNC from a single sheet of clear stock. Installed in the middle of the lid is 1/4" polyethylene clear plastic mesh which is secured by a serrated vinyl retainer spline. If you intend to house smaller specimen (~1/4" diameter or less), we recommend the use of our Evaporation cover, or mesh is also user replaceable if you would prefer to change to a smaller mesh.
If the PREMIUM FEED style is selected, it will include a feed opening/hole in the frame, and also includes a 3D printed cover made from reef safe 3D printed PETG plastic in black (additional colors available for purchase).
The lid is secured in place on your aquarium by a machined lip around the perimeter of the lid. The inner portion of the frame is recessed below the top of the aquarium glass and the outer portion of the frame rest on top of the aquarium glass. The lid can easily be removed in seconds from the aquarium for maintenance or cleaning with no tools.
Cord slots and cutouts are optional and able to be placed either on a straight section of the lid or directly on a corner. Cord slots will protrude into the tank display area 8mm x 12mm.
EVAPORATION COVER: Kraken Reef evaporation covers allow you to have that convertible top option. This removable solid polycarbonate piece is designed to help reduce water evaporation in your aquarium. The cover is secured in place on your lid by a machined lip around the perimeter of the cover, with the inner portion of the cover being recessed below the top of the lid. Note: Condensation may build up on bottom of cover, and reduction of light output into the aquarium (PAR) may occur. Also, weight of the cover may cause deflection in the lid when installed.
PREMIUM FEED COVER: Kraken Reef premim feed covers are designed for the premium feed style lid. A black version of the cover is included when you purchase the premium feed style lid. Additonal colors are available in reef safe 3D printed PETG plastic and a clear polycarbonate version is also available.
FEED CUP: Kraken Reef feed cup is a convenient and hassle-free way to feed. This cup fits inside the PREMIUM FEED feed hole and allows placement of frozen food to defrost while still keeping your inhabitants safe. Multiple colors available in reef safe 3D printed PETG plastic.
