    • Great tank

Great looking tank. Had an issue with the pump after a few days. But the seller sent a new one.

    • Strong well built tank
Size: [60A] - 23.62X14.17 X14.17in
Love the tank and all the included parts except for the prototype head. It kicks up a lot of tank debris and spits it right out making a very cloudy tank.

    • Very pleased! Great quality, even better customer service.
Size: [35A] - 13.77X13.77X13.77in
This is a great all in aquarium. After looking at many I settled on this one due to size and it is all glass. Even the dividers in the filter area and the lid for the filter are glass. I had an issue with the included pump making a clacking noise. I went to the manufacturers web site and filed a customer service request. They responded and shipped a new pump out the same day! You cannot beat service like that. Special thanks to Kimberly at UNS for really taking care of me. ... show more

    • Needs a redesign.
Size: [90LA] - 35.43X11.81X11.81in
Review Image by Jorge V. Jorge V.
I've been shopping for tanks for a while and was drawn by the size and dimensions of this UN aquarium. It's very well built, the glass looks amazing, but there's a big flaw. The design of the reservoir is poorly engineered to where you have to keep the water levels very high or else the pump chamber water levels drop and the pump starts blowing air. Also, the size of the vent holes are really big and I've lost at least 5 tetras that swam in there and died. I had to modify the intake with some plastic mesh to keep anymore fish from swimming in. Lastly, this is a very expensive tank and considering how particular the water levels needs to be, they should have included a lid (especially for the price!) to help keep water from evaporating so quickly. I "upgraded" from a fluval flex 9 that was easily maintained and well engineered, and I was hoping this tank would also be an easy set up. Unfortunately, I will have to figure out and heavily modify this tank to get it to where it needs to be, not to mention an expensive, precisely cut piece of glass to add a lid. It's like an exotic car, gorgeous to look at but annoying to keep running. 🤦🏻♂️ ... show more

It's not a cheap product... why can't you make sure the product is shipped nicely? There were a lot of small pieces of glass everywhere... the corners where the glass meets was super dirty, and there were scratches in the black plastic and in the glass.

    • Really wanted to like it, but regret purchasing it
I bought this as I was a newbie trying to get more into the fish/shrimp keeping hobby so I wanted an “easy” all in one system that looks clean. However, I enjoyed it at first but that quickly went away after a few months. It doesn’t come with a lid so had to purchase that separately which was a substantial addition. The tank itself is very beautiful with the build quality being excellent. However, like most people on this page, the filter is quite terrible and is the main pain point for me. The filter easily gets clogged and doesn’t pump out water. I find myself needing to “reset” it so it works a couple of times a day. If I were to go back, I would definitely not go with their all in one, and purchase everything separately which looks better and is more cost effective. I really tried my best to like it given the negative reviews but I agree with them completely now. ... show more

Get a lid if you want to keep your fish from jumping! Only con is you can NOT adjust water height.
