Build Your Own Long Rimless Aquarium Kit

Designed for panoramic viewing and horizontal flow, our BYOB long rimless aquarium kit lets you create a balanced setup in an Ultum Nature Systems long rimless tank. Long rimless aquariums are perfect for nature-style aquascape layouts, flowing hardscape, and schooling fish. These tanks offer more horizontal ground that requires creative aquascaping.

If your space needs a splash of nature, start by customizing each component of your setup. From the tank itself to substrate, filtration, CO2 equipment and lighting. Every option is curated for compatibility, so whether you intend to create a low-tech aquascape or a densely planted aquarium with the works, you can.
