"This was my first UNS tank. I’ve seen the tanks in- person so I knew exactly what to expect. This was my first time ordering a tank online. I was hesitant to do so but was very happily surprised to open a well packed and protected aquarium. The package was shipped in a double-layered cardboard box with styrofoam padding along each side, and delivery went off without a hitch! I’m excited to order from Glass Aqua in the future"
"First id like to mention how well the tank was packed, thank glass aqua for insuring it arrived safe. The tank itself is pretty nice, I could argue it isn't worth the extra money and you could just put a blue background on a regular 60u but I'm very happy with it. No extra work once you get it home."
"I bought the 60S for an iwagumi project I’ve been planning. The tank is perfectly constructed and the mitered corners are an elegant detail. The glass is flawless. I can’t wait to get this project started."
"This was mothing like what i ordered. I got a tiny little tank with a lid that barely cover half the tank. It was supposed to be a 40 gallon tank with a glass lid. It was maybe a 2 gallon. It was definitely not what i ordered."
"I purchased the UNS 40C for a bioactive terrarium to house my pet millipede, and I couldn't be happier with it. The tank is exceptionally well built, with sturdy construction and a beautifully minimalist design. The glass is crystal clear, and its thickness gives the aquarium a premium, high-quality feel while providing confidence in its durability. It truly elevates the entire display and makes the terrarium look like a showcase piece. Highly recommended if you're looking for a rimless tank with outstanding craftsmanship."
"Beautiful glass aquarium, working on landscaping it and then adding my snails, shrimp, and fish to it after I get it all setup but it looks awesome."
"I really like my shallow fish tank. I recently bought a betta fish and my fish really likes his tank. The tank is super secure and made of crispy clear, high quality pieces of glass"
"Arrived in a timely manner, beautifully made, the stabilizer mat fits perfectly and it was well packed. Very happy with purchase."
"I absolutely love the 17 inch cube and the lite. It’s gorgeous"
"Beautiful glass"
