Hagen Flex Freshwater Kit - Black - 15 gal

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!

After dealing with multiple issues with BiOrb on Amazon, our School at a University decided to go a different route and try the Fluval Flex. It was not a disappointment at all. This is a very spacious and gorgeous tank that was easy to assemble and gorgeous to look at. Admittedly, I did have trouble with the remote to the fish tank light, but that's on me and not the tank (the sensor is at the top so you have to point at it which I wasn't doing). It's really fun to be able to change the colors and dim or brighten them. Very quiet and so far our fish are enjoying the added space. Incoming guests as well as the college students love coming in and watching the fish. Thank you Fluval for being wonderful (and for not being BiOrb)!

The Fluval Flex Aquarium Kit has transformed my space into a stunning aquatic oasis. Its sleek and contemporary design, complete with LED lighting, adds a touch of elegance to any room. Setting it up was straightforward, and the filtration system is efficient, keeping the water crystal clear. The curved front glass provides an unobstructed view of my fish and plants, creating a visually captivating display. However, the provided filter media could be of better quality. Overall, it's a fantastic kit for both beginners and experienced aquarists, offering a stylish and functional home for my aquatic friends. It's brought tranquility and beauty to my living space.

This is a great universal tank. The lights are great for artificial plants. I don’t feel like it would be bright enough for a planted tank. It is just the right size to sit on the counter in the kitchen. The filter on this thing is pretty overpowered. You can make it a shrimp tank but it takes a few 3rd party accessories to tone the filter down. I have had mine for probably six months now, I wanted this to be a pretty stress free tank so I did all artificial plants and natural gravel as a substrate. I’ve got a school of neons, a snail, and some Khuli loaches. I have been neglecting this tank, did no water changes, no tank cleanings, I have only added zero water to replace the water that evaporated. Water is crystal clear. My only complaint is the remote that came with the light is messed up. The button that turns on natural white light doesn’t work. So now I’m on a green hue light. When that one breaks going to put a different light bar in.

Ive had my tank almost a year now and its been great! The internal built in filter is low maintenance (rinse the medium now and then). It keeps my tank nice and clean looking and is very quiet. Ive never had any water parameter difficulties. I use black sand as a substrate and the filter has never picked up particles. Its very well made and looks/feels luxurious.I do need to take a star off because the built in lights started malfunctioning after about 6 months. It constantly flashes dark blue lights at random when lights are switched off. Ive tried every setting and unplugging, but nothing stops the lights except turning the lights on intentionally. It doesnt impact functionality at all and I have gotten use to it, but I do worry about the longevity of the LEDs with blue lights always flashing for no reason.
