Good buy
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.

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

Great product!
Excellent deal considering what it comes with, I couldn't find any other kit that came with as much stuff! I did buy 1 more plant and a hiding place for my ghost shrimp. Some one said the plants look fake, but they are supposed to as they are part of the "Wonderland " series. That being said I'll admit they look good under they changing light colors. The filter is great and it provides plenty of water movement and it's pretty quiet(it was noisy for the first 30 seconds until it worked all the air out of the turbine), the only noise to come from it now is the water cascading off of it. The heater seems to work good, although I purchased this tank as an upgrade for my 2 goldfish so I don't use the heater in this tank. I use it in their old 3 gallon fish tank with a betta. It keeps the water at an even 77 degrees F. I would recommend as some add ons; gravel, some kind of starter bacteria to cycle the tank faster, some more plants /decorations, and more water conditioner/food after the samples are used up. The instructions for the hood do say to clip the lights into the hood, but these lights (at least for the color fusion) are a different type that come with their own instructions which is easy to install and one that I prefer so when I open the hood I'm not blinded by the led lights. One other thing I would recommend to get if you don't want to wait to add fish is nitrifying bacteria such as marineland's bio spira that should cycle your tank in <48 hours.

Great Tank, Like Hinged Hood. Make Sure Pump Tube is Pressed Down Tight.
There are several components to this aquarium to review. Firstly, the tank itself. It seems made well, simple enough. Now the hood. It has perforated cutouts for a filter and such. It also has a rectangular feeding hole near the front. There are extra spaces in the back for the light cable and air tubing if so desired. The lights actually have to be placed into their respective slots on the underside of the hood and there is a channel for the cord. The light cord can come out the left or right side, depending on preference. There are also 2 hinges that need to be installed. We found installing them onto the hood first worked easier than putting them on the tank's rim first. Just make sure that the front lip of the hinge clip (shorter side) goes under the tank's inner rim or the hood will not go down flat/sit flush. I like the hood overall, but I am concerned about the light strips constant contact with water. They're not submerged in the water, but they stay wet nonetheless. The heater is not being used, so I can not comment on that. I did stick the exterior temperature strip on the outside of the tank. Now onto the other accessories. The fishnet is basic, simple. Tjere is also some aquarium starter to make tap water safe and a small sample of fish flakes. I highly recommend having your own fish food and aquarium solutions. The decor is sparse. They actually gave me the wrong decor for my tank. I did get the boxwood gravel mat, but the rest of the plants that were in my kit were the "GloFish" plants. They're really bright and cheap looking and are better suited for the GloFish version kit, which they are actually intended for. If I had wanted the GloFish accessories, I would have chosen the GloFish kit. All the rest of the decor in my picture was from my smaller aquarium or ones that I purchased separately. I'm glad I had my own stuff because the included decor is pretty chinsy. Lastly we're onto the "Whisper" filter system. Whisper is a bit of a stretch, more like humming filter. As you can guess this is not as quiet as they make it sound, but it is tolerable... well at least now it is. I did have an issue w/the filter being super loud for days. I was so annoyed because it sounded like a small aircraft taking off in my dining room and it could be heard throughout the house. I almost dropped the star rating severely because of the amount of noise this thing was making. I decided to tinker w/the filter system again to see if I got a defective one or if it was some other issue. I'm glad I did because it's way more quiet now, not a Whisper, but definitely not obnoxious. The tube that presses down into the pump had somehow gotten slightly loose. This was causing vibration and also the pump gear wasn't catching like it should. The result was the filter was super loud. Once I tinkered around and pulled the tube back up and pressed it back in until it clicked, then the noise dropped drastically. Also, I found that I can not use the bio sphere filter type mediums in the back of the filter either because they cause vibration too. The pump comes w/1 Large size filter. Make sure to buy/order more of those too for monthly changes.

Great tank, hard to find replacement lights
This is a fantastic tank. I purchased it in September 2022, and set it up in October. I haven't had any issues with it, and the same fish I bought then are still happy and healthy! As of today though (July 30th 2025) the light strip has started to flicker and shut off on its own. I have been looking for replacement lights, but the lights in this hood are very unique and I cannot seem to locate a replacement. After searching Amazon, customer reviews, the Web at large and the company site, I still haven't located this particular light strip. I did call and left a message with customer service as it's after hours over East where their headquarters are. I hope to hear back soon with some options, but am wondering if anyone has had to replace the light and may have other resources?

Broken filter, bad fake plants, 5 stars!!!
So let me start with the bad. The thermometer is a plastic stip that doesn't work. The horrible plastic plants will hurt most fish. The filter was broken and sounded like a bunch of rocks were grinding inside it. And the light is a super basic on off. Now why you should buy this over all the other tanks. That's the tank and the price. The tank is a perfectly functional 20 gal fish tank. It has a nice lid. And I was surprised I liked the heater. All this for less than what a 20 gal fish tank without a lid would normally cost. Seriously just replace the stuff you don't like. The tank alone is worth the price. My tank has been set up for a month now. Photo attached.

Refused to help me. An so much broken and wrong
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

Decent starter kit
The tank itself is ok but the accessories that come with it seem rather cheap. I replaced the pump, heater, and thermometer with higher quality products. I guess it kinda defeated the purpose of me getting an all-in-one kit 🤷♂️

Buenísimo, mucho más de lo que esperaba
En realidad no me fijé que traía tantas cosas y esperaba solo una pecera. El kit trae muchas cosas muy buenas para los aficionados a los peces. Muy buen precio.

Buena pecera. La lampara es de mala calidad. El resto, bastante bien.
Ojo. Viene sin grava. Hay que comprarla por separado. Algunos adornos son demasiado plásticosos. Compre algunos otros por fuera también. Tiene buen tamaño para comenzar. Buena calidad. La lámpara no se puede conectar a un timer o accesorio, ya que forzosamente se debe usar el botón de encendido de la lámpara para poderla encender. La lámpara deja de funcionar después de 1 mes. El resto de la pecera está muy bien. No he tenido ningún tipo de problema en 8 meses de uso
