The media could not be loaded. This is a 21 gallon tank, it is beautiful. It was delivered safely and on time, there are no problem, it is working and holding up perfectly, and no leaks, the clarity of the tank is perfect, my husband set it up in our kitchen and I'm enjoying it so so much 😀 I definitely would buy again from this company and yes, I would recommend this to all. ... show more

  • Gorgeous small aquarium
This concerns the 4.1 gallon size aquarium, which arrived today. It's stated as a 10 inch cube, but that's approximate. It's actually metric, 25 centimeters along each edge. That 25 cm is correct, according to my tape measure. In inches, it's 9.84, if anybody cares about the difference, which I don't. The glass thickness is 5 millimeters, by my actual measurement. It was very well packed. When it arrived, one edge of the carton was dented, which worried me. No problem, though. Inside the carton, the aquarium was protected by a top cap, a bottom cap, and stiff edge protectors, all surrounded by a thick layer of styrofoam peanuts. So despite the dented carton, the aquarium was fine. Styrofoam peanuts are a nuisance because of static electricity, and they shed tiny particles, but they do a great job of protection, and that's what counts. The aquarium looks perfect. I examined it very carefully, all the sides, the bottom, all the edges, both visually, and by running my fingertips along the edges. No roughness or unevenness, no problems at all, that I could find. Flawless. When I was chasing tiny particles of styrofoam with a moist paper towel, I noticed the glass was squeaky clean. That's exactly what the whole aquarium looks like, a pristine cube of squeaky clean glass. It passed the initial exam with flying colors. I'll check it for leaks by adding a little distilled water now and then over the next couple days. Based on how well made it looks, I don't expect any problem, but if it leaks I'll edit this and let people know. I think my Betta is going to be a happy camper pretty soon. ... show more

  • UNS does not disappoint!
Pattern Name: Nano Size: [5N] 4.6 Gal 14.17 x 8.66 x 8.66
UNS tanks are excellent, I have 2 pico size. The silicone work is super clean and overall the tanks come well packaged, clean, and clear. I rarely give 5 stars, but I can't find a single thing I don't like.

  • Most beautiful tank
Pattern Name: Long Size: [45L] - 3.4G / 13L - 45x17x17 CM
I’ve been looking for a bookshelf tank since forever that was a good price and I finally found one! It’s durable, no cracks, and my betta loves how wide it is in comparison to his 5g cube.
