I wish it was bit longer instead of taller. Most of your gallons are in height but the tank itself is beautiful and my sharks love it. Easy to clean and the heater that comes with it works great to keep the water warm. I have no leaks or cracks and the filter that comes with it works good. It is a bit louder than other ones but it puts in work. And had a great waterfall sound. It is decently heavy so be prepared to lift with your knees. All in all it’s a great tank and great size for little tetras and angelfish. ... show more

This was my second aquarium set. Tank is good, lid is good but the filter makes a lot of noise and replaced it.

    • Holds Fish AND Shrimp
Color: Color Fusion Size: 20 gallon
The pump and lights sucked, but it's a pretty decent aquarium. I'm enjoying it. The pump works well enough, but you have to reset it or clean it constantly or else it will hum like a drone into your mind... driving you mad. I just replaced it and the light. The light bar they sent cannot be used with a timer because of the power switch setup. However, I still think it's a good value because it is shipped very well and arrived safe and sound. The aquarium quality is as good as any other. There's not a beautiful finish on the rims, but oh well. ... show more

    • GREAT TANK
Color: Color Fusion Size: 20 gallon
The media could not be loaded. I bought this tank for my two daughters, ages 4 and 7, who were interested in getting some glo fish. Originally the plan was to go with two small tanks for each of their rooms but quickly learned this was a much more cost effective option as well as more likely to have happy fish and be visually appealing. We liked the look of the Color Fusion versus the Glo Kit because of the color changing option. We have had the tank set-up without water for a couple weeks, finally filled it up and got the filter and heater going yesterday, and have made 6 GloFish a home today. This works really well with GloFish, for those that might be wondering. After a lot of shopping for tanks, I went with this kit because the reviews were positive, the price was right for what you get, and the customer service responses were encouraging that if we had any after purchase questions and needs, they would be taken care of, and they have been. This tank comes with.... - A pump and filter. It is quiet other than the water movement, which is actually quite relaxing. You need to change this monthly from what I understand. It has a low and hi setting. - A heater. It is not adjustable but seems to be holding the temp just fine for our Tropical GloFish. - A Color Fusion light. It cycles through the colors, you can press the button to halt in on a color if you wish. There is not an off button, so if you want the light off at night you will need to either unplug it or put it on a timer. So if you are counting that is 3 outlet openings that you will need and you should probably have this going to a ground fault outlet, which we did. - Comes with a few Color Fusion decorations and a really nice sea anemone decoration. -A net, a little packet of water conditioner, and a small packet of fish food. -A Thermometer - ours was missing this, but the company was really helpful in getting that resolved. What you will need to get: - You will need to get some more decorations for sure. No gravel comes in the kit. I bought a total of 34 lbs of gravel, All black for the base and then 2 - 2lbs of color glo gravel, and 2 small bags of gem rocks. - More fish food and water conditioner - A gravel vacuum - A background for the tank. I used black Cricut Vinyl. - The FISH :) April 2019 EDIT: After an estimated 9000 hours the light has quit working. We leave the light on about 12-14 hours a day and shut it off at night. I am attempting to contact company to see about a replacement. I am not finding what they state the life of the light should be, however, other companies that sell similar lights claim a guarantee for 50000 hours. I will let you all know what I find out. After finding a couple different contact emails with various responses one sent me a replacement light. We have the new one on a timer that is one 8 hours per day. We have a llevo and 5 Flo fish in the tank. And pleco like dark to get out and eat that algea so that is why the light settings ... show more

I reached out to company by phone and their contact sheet. No response. Clamps broken on light. Light is wrong light for the tank. Doesn’t fit under the lid at all and can’t go on back of tank due to filter and can’t go on side of tank due to its to long for the side. It’s fully not what’s advertised at all on the lights or how to install at all. The material is flimsy for lid and lid and clamps to lid are broken on one side and lid is cracked. Was a birthday gift I got bc my birthday is this week. Can’t send it back bc I don’t have the box. Figured it would all be new and nothing broken. I even went out and bought new items and rocks and new filters and lucky bamboo to add next week. Just tried tonight to finally take it off the counter and look at it and try to see if I could get it ready to cycle. Noticed the crack in the lid first. Thought okay it’s fine. Won’t be a big deal but nope then notice the lights are not even the right lights for the tank at all. Like no comparison to what’s suppose to come with it. So now I have cracked lid and no lights at all. Not to mention two clamps were broken as well. One for lid and one for the light that doesn’t even fit this tank. So I stopped their and didn’t even bother to look at the rest. Just done and out 160 plus dollars for a twenty gallon tank that has no lid and no lights. I could have bought a 20 gallon at pet store for 20$ on sale for what I got for this. If I could give zero stars I would for lack of communication and failure to help ... show more

    • Noisy pump. Bad design for light strip.
Color: Tetra Size: 20 gallon
Review Image by Ignatowski
The filter/pump is noisy! My previous was a Topfin pump, very quiet. I ended up getting a different pump, much quieter. Basically, no instructions. If this is your first setup , I’d choose another. Had no clue where or how to attached strip of lighting. I had to call company. The guy was very nice and helpful. I don’t care for the way the light stop is just above water and wire is to close for my liking. The ISO’s of pump (for 29 gal) doesn’t leave much room for light strip to be attached. Where the electrical plug set up is doesn’t seem to be very strong for too many pulling out. It looks great setup but I’m not very thrilled with it. ... show more
