UNS tanks are the best
"UNS tanks are the best, glass is great, sizes are always great, never had a leak (I have 3 of them, all different sizes), & glass aqua has the fastest shipping for the UNS brand tanks which are already fairly hard to find."
Ultum Nature Systems standard rimless aquariums offer an elevated take on traditional tank formats, supporting a wide range of aquascaping styles. With subtle adjustments to classic proportions, UNS standard tanks provide a versatile canvas for building complete aquascape layouts with signature foreground, midground, and background composition.
This format is great for nature-style planted aquariums, allowing for flexibility in plant selection, hardscape structure, and overall layout design. From simple aquascapes to contest-ready displays, standard aquariums make it easy to try different nooks within the hobby. The UNS 60U has become a go-to size for many aquascapers, offering a balanced footprint that’s manageable to maintain while still providing enough space to create beautiful planted tanks.
Available in a variety of sizes, standard aquariums remain a pillar for hobbyists looking for a well-rounded, adaptable tank that balances design, form and function.
Like all UNS aquariums, each tank is crafted with ultra-clear low iron glass and clean, minimalist lines, offering a refined foundation for your next freshwater planted or saltwater reef aquarium.

"I’m really impressed with this UNS rimless tall glass aquarium. The glass clarity is excellent—super clean, no distortion, and really makes everything inside pop. The rimless design gives it a modern, minimalist look that fits perfectly in any space. The build quality feels solid, with clean silicone work and sturdy construction. I especially like the tall profile—it’s great for aquascaping and creating depth. Only thing to keep in mind is that because it’s rimless, you’ll want to be careful during setup and maintenance, but that’s expected with this style of tank. Overall, definitely worth it if you’re looking for a clean, high-end aquarium."
"Beautiful aquarium. Love the chamfered edges (or mitered cut, as they call it). Only thing is that it came with some small scratches, but nothing I’d fuss too much about. Then i noticed a few more scratches. I have been dry-scraping to see what look I want, so I’m sure I do it, but I’ve been very careful and I’ve done this with several tanks in the past that didn’t scratch as easily. Maybe its the ultra-clear glass is more prone to scratch, I dunno."
