What makes Ultum Nature Systems aquariums different from other brands?

Ultum Nature Systems aquariums stand out for their exceptional craftsmanship and minimalist design. Each tank is constructed using ultra-clear, low-iron Diamant glass, which delivers over 91% clarity and eliminates the green tint found in standard glass. The tanks feature 45-degree mitered edges and minimal silicone seams, offering a sleek and seamless look that highlights the beauty of your aquascape or reef setup.

Are UNS tanks suitable for beginners?

Yes, UNS tanks are suitable for both beginners and experienced aquarists. While they are favored by professionals and aquascaping competitors, UNS also designs products for ease of use. Their All-in-One (AIO) and Foresta lines come with integrated filtration, misting, and lighting systems that make setup straightforward for new hobbyists looking to start with planted tanks or paludariums.

Can I use UNS aquariums for reef tanks?

Absolutely. UNS aquariums are compatible with saltwater and reef environments. The R-Line Reef Systems are particularly well-suited for this purpose, as they include built-in sump filtration, marine plumbing, and additional features like auto top-off reservoirs and cable management systems. The clarity and build quality of the glass make them ideal for showcasing corals and marine life.

What size options are available for UNS tanks?

UNS offers a wide range of tank sizes to suit different needs and environments. These include compact nano cubes, standard rectangular models like the 60U and 90U, shallow designs for low-profile aquascapes, and full reef systems with stands. There are also Foresta paludariums in several sizes, allowing for creative displays that combine land and water elements.

Do the tanks come with lids or covers?

Most UNS tanks are designed to be open-top, which enhances their modern appearance and supports natural gas exchange. However, optional glass lids and clear acrylic clips are available for purchase. These accessories help reduce evaporation, maintain humidity in paludariums, and offer added safety in homes with pets or jumping fish.

What is the Foresta Paludarium and how does it work?

The UNS Foresta Paludarium is a unique system that merges terrestrial and aquatic habitats into one display. It includes a built-in misting atomizer to maintain high humidity levels, an internal filtration system to manage water quality, and LED lighting to support plant growth. The Foresta is ideal for creating biotope environments with mosses, orchids, amphibians, or semi-aquatic creatures.

Are UNS tanks pre-drilled for plumbing?

Standard rimless UNS aquariums are not pre-drilled, which preserves their clean aesthetic and allows for flexible use. However, the R-Line reef systems do come pre-drilled and include full sump filtration and plumbing components. Aquarists who wish to modify standard tanks can add external overflow systems or use hang-on-back filters depending on their skill level.

What accessories are recommended for UNS tanks?

UNS manufactures a range of high-quality accessories that integrate seamlessly with their tanks. These include external canister filters like the Delta and Blitz series, CO₂ regulators and diffusers for planted aquariums, mist makers for paludariums, precision planting tools, and LED lighting systems. These products are designed to maintain the minimalist visual appeal while delivering professional-level performance.

Are these aquariums easy to maintain?

Yes, UNS aquariums are designed for low-maintenance operation when paired with the right equipment. The glass is easy to clean and highly resistant to staining. Using proper filtration, lighting, and CO₂ systems ensures water quality and plant health, making long-term care manageable even for new aquarists.

Is there a warranty on UNS products?

Yes, UNS aquariums come with a standard three-year warranty, which can be extended to five years when the product is registered with the manufacturer. R-Line reef systems and other advanced setups may have separate warranty terms for components such as stands and plumbing parts. We recommend keeping your proof of purchase and registering your product for the best coverage.
