Review: Perfect! - I’ve been out of the aquarium game for years due to nursing school, work, and health issues but now I can finally breathe again and I decided to jump back in!! This was the absolute perfect tank to start back up with. It’s pretty quiet (you hear it but it’s not obnoxious!) and it’s simply beautiful. The design is clean and I love the curved design with the lid. The lights are super customizable and dimmable. Everything works well together and it is a thoughtful design. While I don’t love losing space to the back (filter and pump), I can hide the heater in the back of the tank so that is a bonus. Assembly is easy and very straight forward. The water flow doesn’t seem too much to stress the fish out either. Overall a really solid design and a beautiful tank especially for those just starting out.
Review: Beautiful! - Nice sleek design. Lots of room in the back for a heater, bubbler, etc. (I even managed to fit a sponge filter seeded with bacteria from a well established older aquarium in the back to speed up the cycling process (from Angels Plus) The lights are nice. 15 different colors plus a white light with a dimmer switch for all lights. The night time setting is pretty and will make glofish products glow nicely. The lightning setting is novel but I can't see leaving that on much. It just flashes white light like lightning. Kids may like it though. My favorite is the button that cycles through all the colors slowly. I recommend getting a 3D background for this tank before you set it up. The background is black and not all fish look that good against a plain black background. Especially dark colored fish. We got The Underwater Treasures 3D vine background and I could not be happier with it. (Easy to cut to fit this tank and looks fantastic) Only problem we had was that some of our tetras fit through the slits in the intake vents and ended up in the back filter part of the tank. It was pretty hard to get those buggers out of there. Once they were out I put some sponge material over the vents and that seems to have solved the problem. (The sponge fits into the square for the vent that we cut through the background and the background keeps the sponge in place over the vent. I'm not sure how you would solve this issue without a 3D background.) Overall I love this tank and couldn't be happier with it Update 2/23/18 Ive had this tank for almost a year now and I still love it. The only problem I had was about 2 months ago the pump got really slow so the water was barely moving through the filter. I took the pump out, took it apart and cleaned the small sponge around the intake inside the pump (not the big square filter sponge in the back but the tiny one inside the pump itself) and it fixed the problem. (Is it in the directions somewhere to periodically clean the pump itself out? because I completely missed that) anyway...everything is back to normal now. I still highly recommend this tank...Just remember to clean the little tiny sponge inside the pump from time to time.

## Questions & Answers

**Q: Does this tank truly hold 15 gallons of usable water for fish?**
A: Absolutely not. The person who answered saying yes is wrong. I measured after decorating my tank and it only holds 12 gallons. Plus you have to consider the back panel is missing so there is less swim space. This really is more of a 10 gallon tank.

**Q: Does 15” depth represent the dist. from the back to the front of the bottom of the tank or from back to the most forward part of the curved face?**
A: It's 15" tall (floor to ceiling) by 15 inches deep (front to back) by 16" wide (left to right).  Hope that helps.

**Q: What all will it come with.  (heater pump. filter. media. etc?**
A: This aquarium comes with an LED light built into the hood, pump, and filter with media.

**Q: can someone give me the dimensions of the filter compartment?**
A: It is 4.25" x 3" (this is just the portion that houses the filtration system)

### ⭐⭐⭐⭐⭐ Fantastic!! I Love This Aquarium!
*by L***R on April 15, 2023*

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!
