  • Fantastic!! I Love This Aquarium!
Color: Black Size: 15 Gal.
For many years, I kept saltwater, brackish, and freshwater aquariums on a pretty large scale. I took a break from the hobby, and recently found myself ready to get back in the saddle, though on a smaller scale. I chose this aquarium for the Fluval name-- I had great prior experiences with Fluval filtration (loved my Fx4!!) This aquarium reignited my love for Fluval. Super quick and easy set-up, attractive, so quiet that you can't hear it running, and the lighting is really sophisticated-- fun to personalize the light settings!! I was pleasantly surprised by the technological advances (and reduced costs) offered by this aquarium, since I was last active in the hobby. Overall, I give this 5+ stars. I plan on buying this set-up again for my parents (and setting up another one for myself!). I do, though, have some suggestions to Fluval, as an experienced aquarist, as to improving this already great aquarium-- 1. The food slot in the front of the tank lid would benefit from having a sliding or hinged door. My cats sit on top of the tank and were easily able to get their paws in, until I installed a mesh cover. 2. It would be nice to have the top hinged, so it would be supported whenever doing water changes. 3. Even though this is a relatively small aquarium, I can see that there might be times that you might want to use additional equipment with it, such as a chiller, sump, or UV sterilizer. However, the current lid design, head space, and design of the partitions between the back chambers doesn't support this. It would be great if those areas could be re-designed to provide flexibility to use additional equipment, as needed. Overall, though, I adore this aquarium!! Already planning my next Fluval Fex 15 gallon tank. Stay tuned! ... show more

  • Good tank, quiet
Color: Black Size: 9 Gal.
Nice tank. We clean it with a vacuum, so the 'tender breakable glass", well, we don't tip it up to dump and clean so not bad. It now comes with extra clips with smaller slats to cover the intake ports. If you have anything bigger than fry it will not suck them into the filter. If you're breeding fish, get a breeder net. The power is a bit much, but not bad. We have tetras and they make it just find. It looks good, and it is not loud at all. It's acutally super quiet. The remote has crazy light combo options. So much the kids like playing with it. I don't get the storm feature but whatever. Overall, great tank, looks awesome, quiet, good flow. We're happy with it. ... show more

  • Such a pretty tank!
Color: Black Size: 15 Gal.
I bought a used tank for cheaper, which I was weary about because what if it was cracked or damaged or had a leak? I rinsed it out and put water in it and so far so good (it's on the cycling process right now), but then I realized that the pump wasn't working for me! I put it in different outlets to try and see and it still wouldn't work. I messaged the company and two days later, they responded, but they sent me a new pump for free! So they were a very nice brand to get ahold of and didn't even question it when I asked what I could do. The lighting works great. Their pump water flow was pretty strong so I did what another reviewer said and I bought those foam things to put on top of them, also from the brand fluval, which really slowed it down. I also bought the 15 gallon heater that fluval offers, which I bought used too, and it works great. Some reviewers mentioned the hole at the top, but if you have floating plants that can cover that space, I'm sure it wouldn't be an issue. Or get a piece of mesh if it's bothering you. It's really not that big and if your betta jumps through that, you might want to invest in teaching it to do some tricks because that would be impressive (I can only say that for the 15 gallon, I don't know about the 9 gallon). Anyway, I love my new tank! ... show more

  • I LOVE THIS TANK!!!
Color: Black Size: 9 Gal.
I got this about a month ago and was worried my delivery guy would shatter it like my last one. However, the packaging was SUPERB. Not a crack, scratch, or leak! I have housed a bunch of ember tetras and cherry shrimp in here and it’s super spacious and I love the hidden mechanics! The outflow filter is EXTREMELY strong though, so be wary of what fish need currents and which struggle in them. I was able to turn the flexible nozzles to hit the walls and stuffed a thin piece of sponge to help with the strong current. Overall, this is by far my favorite tank I’ve ever purchased. It’s super sleek and efficient! ... show more
