Review: Fantastic!! I Love This Aquarium! - 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! Review: Nice quality tank! - I really like this tank! I was looking for a nice small tank for a planted aquarium. The bow on the front really makes the tank unique and adds a sharp expensive look to the tank. The quality of the glass is nice and the black beading on the back wall and the top rim of the tank really helps clean things up. It nicely hides all the equipment and pumps in the bank and give a nice look to the waterline. The light fixture came DOA, but the seller quickly replaced it and it is now working great. The light is bright and provides a lot of custom options. It may not be the strongest light for a planted tank, but sure looks like it will be more than enough for the plants I am growing. The real compartments are large enough for your own mix of equipment and filter media. The grates on the intakes are a nice touch and will keep small fry or shrimp out of the rear compartments. I added some small filter material inside these grates to further decrease the chance of fry or shrimp entering. The pump is quite strong and is completely silent. I cannot hear it run at all. The tank sits next to my bed and you wouldn't think it was even running. The tank also came with a nice mat for the bottom glass. Overall I am extremely happy with the tank. Ignore the bad or misleading reviews. Perfect planted tank. Great quality and a great price point. Thanks! ## Features - Stylish Fluval Aquarium: Contemporary design with curved front and honeycomb wrap that conceals water line and filter compartment sides - Customizable LED Aquarium Lights: Fully adjustable 7500K White + RGB LEDs for endless color blends and plant growth support; FLEXPad remote for special effects like lightning bolts and fading cloud cover - Powerful Fluval Fish Tank Filtration: 3-stage filtration with oversized mechanical, chemical, and biological media for superior water quality - Perfect Pet Supplies: Small fish tank enclosure with multi-directional dual outputs for customized water flow; easy feed top cover opening - Innovation for Fish Keepers: Fluval innovates to foster a sustainable future where aquatic life and humankind can thrive in harmony ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01MRIQW7K | | ASIN | B01MRIQW7K | | Age Range Description | All Life Stages | | Best Sellers Rank | #51,069 in Pet Supplies ( See Top 100 in Pet Supplies ) #204 in Aquarium Lights | | Brand Name | Fluval | | Color | Black | | Customer Reviews | 4.4 4.4 out of 5 stars (3,664) | | Date First Available | November 18, 2016 | | Date First Available | November 18, 2016 | | Directions | Follow individual packaging instructions. | | Included Components | Hagen Flex Freshwater Kit - Black - 9 gal | | Is Discontinued By Manufacturer | No | | Item Dimensions LxWxH | 13.19 x 13.78 x 12.8 inches | | Item Package Dimensions L x W x H | 18.07 x 17.28 x 16.14 inches | | Item Weight | 5.04 Kilograms | | Item model number | 15004 | | Item model number | 15004 | | Manufacturer | Rolf C.

Mine broke **Q: What is the honeycomb pattern on the front in the pic? Is that actually on the glass?** A: There are two places on this tank with the black honeycomb pattern. The first is on the sides of the tank towards the back. This is to hide the filters, pump and others items you can stash in the back section of the tank. Fluval did this to alleviate sightly issues. In generics tanks, the filter, pump and heater are in full view in the tank. Many aquarists find this unsightly, and specifically buy fluval aquariums because of the added astetics the back hidden area provides. There is also a second area where you can find the honeycomb print, which is around the top of the tank. Again, this is for astectics and it hinds the water line around the tank. The honeycomb pattern is on the external side of the tank and is actually on the glass. Combined, both honeycomb patterns provide a seemless tank astectically and helps the eye focus on the contents of the tank (i.e., fish, plants, decor). **Q: Can the honeycomb pattern around the top of the tank be removed?** A: I was able to use regular Scotch tape on it to remove it. No residue, but it takes a bit of time for the pattern to adhere to the tape. So you gotta be patient. I also used a penny, which didn't cause scratches at all. Im sure a guitar pick would work better, and risk no scratches. I only took half off though, bc I like the pattern as a block for water lines. **Q: Can I put a sticker on the background and it show through the tank?** A: No , it has an integrated sump accross the entire back of the tank. You will need an in- tank background for this unit. Although the back is a nice black plastic panel that looks good as is. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fantastic!!
