Koller Products 5-Gallon Aquarium Kit with LED Lighting and Power Filter, Ideal for a Variety of Tropical Fish

I love this aquarium. It is the perfect size for my small desk and perfect for college students who want a little pet fish to keep them company. It only takes up a little space, but it is very spacious for the fish to swim around. I also really enjoy that the filter that is included only takes up a little space in the tank. The light that comes attached to the lid has so many different colors and light settings. The aquarium was very easy to set up and do water changes. This fish tank was effortless to set up in as little as a couple of minutes. This tank is excellent for its price as well as for its size, and it is a great value for your money. My betta fish, Bubbles, really enjoys his new home and is thriving with all the swimming room he has. You do have to be careful when cleaning the walls as it is acrylic and can scratch easily. The shipping was relatively fast, and the aquarium came in perfect condition. At first, I was a bit skeptical with some reviews saying that the light didn't work and the filter stopped working as well after a couple of months, but I was pleased that my light and filter are still working perfectly after four months, and it is going on strong. Although the filter didn't work right away, it did take a couple of minutes to see the water flow out of the filter. Overall, it is a really great purchase, and if I get another fish, I will buy another as the aquarium quality is excellent for how much I am paying. This product is a 10/10, and I recommend it to others looking for an aquarium around this price range.

Well, despite the reviews of people having problems with the LED lighting I purchased it and looked over the lighting system very carefully before I set up the tank. It looks like they have changed the LED set up from earlier versions of this tank. The power/program selection button has been relocated to the opposite (right) side of the tank and several 'new' lighting modes and timer modes have been added to the LED unit. There is an addendum sheet in the box that has the directions for the 'new' LED functions. Water proofing for the LED array inside the tank looks improved as well. So far, over several weeks of operation, the LED array is still dry even though the protective cover over them will build up condensation. I added a 25 watt submersible heater to the tank along with the other items needed for setting up a new tank. The heater power cord went through the same as the spot as the filter cord and both fit without jacking up the lid. The filter is small and quiet and super easy to disassemble and clean but a word of caution. I put 12 neon tetras in the tank with a beta and after 12 hours 6 of the tetras had vanished. I found them trapped and dead in the filter after having been sucked in through the slots. The slots are no bigger than those on other filters so I think that the tetras smaller size is what allowed this. I fashioned fish guard from a piece of fiberglass screen material from a local hardware store and affixed it to the filter with a couple of zip ties. Replaced the 'missing' tetras and 2 weeks after all 12 were still there. Some people have mentioned that this tank scratches easily, well it will if not cleaned properly any poly-carbonate or acrylic tank will scratch easily compared to a glass tank. Use clean microfiber cloths and cleaner for plastic glasses lenses and you'll be fine. Be careful with tank gravel cleaning, don't slide it along the tank walls!

Just got my tank from postal. Got it all put together filter is ok i guess doesn't make noise. The led light button came all ripped up, the rubber on top just ripped up and or missing. figured its fine that doesn't matter too much at all. Plug in the hood of it and the LED's don't work at all. Not even a flicker. I knew there were a lot of bad reviews but I figured there were also a lot of good reviews and it look decent/price is good. EDIT: I did call the company from the number inside the box and they sent me a new led strip (and improved from the gross old LED's to the newer version) and a new transformer all for free. It was very easy the lady took my name and address and it came in the mail 1 week later. Haven't installed it yet because all of a sudden one day I came back to my apartment and the leds were on. Don't know how but they work most of the time now. EDIT: It's been over a year and the tank is holding up minus the fact I have gone through 3 of the light bars and i am trying to get my 4th right now. I dont know why they keep breaking LEDs are supposed to last an extremely long time.

We got this for our betta fish. It's our first fish. After about a month, the filter was making a strange noise and then stopped working. I reached out to the Koller customer service. They were awesome. They very quickly sent us out a new filter. We left the original filter unplugged for about a day and then tried plugging it in again while we were waiting on the new one to arrive and it started working again. If yours is acting weird, make sure the water level is high enough. We got this heater with it: https://www.amazon.com/gp/product/B07S1WXJ3F/ref=ppx_yo_dt_b_asin_title_o03_s00?ie=UTF8&psc=1 It perfectly keeps the tank at 81 degrees. We initially got this heater and it made the water too hot: NICREW Submersible Aquarium Heater, Shatterproof Adjustable Betta Fish Tank & Turtle Tank Heater, 25-watt Be careful not to overfeed your fish! We definitely were overfeeding ours initially and it stopped eating. We had to fast it for several days and then started feeding it daphnia along with its other food. The best advice I saw was to feed it food the size of its eye, twice a day. We fast it one day a week now too. And feed it daphnia all the other days in addition to regular betta food.

Love it. Perfect for out Betta.

Well. We've used it for two months now and the pump went out. The tank itself is good. However, with the pump going out and the functionality of the lid, I can't get a hang on pump and have to get a submersible. It just cuts my options. The pump worked while it worked and the tank has been thriving with a betta, amano shrimp and ramshorn snails. Definitely feel let down by the pump.

Do not buy! The tank is curved at the edges and completely distorts you view. Basically, you can only look at the tank if standing directly in front. Not to mention the “filter,” if that’s what you want to call it. It’s a complete piece of junk. It doesn’t circulate the water AT ALL, and the water in the tank turned brown less than 3 days after setting it up. Had to go out and buy a Tetra Whisper filter. The only nice feature about the tank is the options to change the lighting. Aside from that, I would give zero stars if possible.

Tihis is working well. I love this small 5 gallon tank !

The 5 gallon size is Mia leading. Accommodates not more than 2 Please make sure to convert to ac voltage before u plug in Size is about 1 ft x .75 ff x .75 ft total Waste of money

It’s not 5 gallons. It’s too small

Muy buen producto. Mi pez está feliz. Muy fácil de instalar y mantener.

La pecera es muy buena, lo único que no me gustó es que el acrílico se ralla con cualquier cosa, la lave para cambiar el agua y quedó toda rayada y se ve opaca
