biOrb Flow 30 Acrylic 8-Gallon Aquarium with White LED Lights Modern Tank for Tabletop Display, Black

Pros: very quiet, ultra clear, practical dimensions, easy to set up, bright light, sleek design, would look good with a variety of interior design styles. Cons: light isn’t dimmable (worried it’s too bright for my betta), limited access via cover in the top, pump only has one speed, view distorted at curved corners. This is a great small aquarium, my betta seems to be very happy since moving in. It wasn’t apparent from the description and photos that I would be able to run the heater cord through the lid, but there is a small hole just behind the power cord connecting the light that fits the heater cord perfectly. The minimal design is unobtrusive and the filter pump is very quiet.

I absolutely love this tank. This is my 4th BiOrb tank. I really like this best because it has a larger hole in the top so I can fit a bigger centerpieces in it. This gives you more options for decor. I like that it has a full view on three different sides. I like that the one side is black to camouflage the heater. This tank is home to my samurai betta, snowflake, he seems to like it. All the biOrbs are so easy to set up. I think they are so classy looking. I’m hoping to get a bigger one some day.

Big pros: everything comes together, optional decor that covers the filter nicely, no need to search for different aquarium parts to cobble together, you know how much you’re going to spend because it’s a kit. Also, the filter is easy to remove and clean if you’re using the right size of rocks and stratum Big cons: the filter would be terrible for fluval stratum so no aquarium plants with deep roots or shrimp hiding places if you have an aggressive fish like a betta; the light and shape distortion on the corner of each face is annoying. Overall, this is a good kit for the size and what you get. I hadn’t put together a tank in 20 years so I wanted something easy. This is a nice decoration piece in my living room but I wouldn’t buy this again because of the corner distortion. I would have gone a little larger with a 14 to 20 gallon tank so I could have a larger number and more diverse type of tank creatures and a different filter setup for fluval stratum. I have had ZERO algae issues. Keep at least a couple different kinds of plants, keep a couple of nerite snails, and keep up with sampling your water (the API chemicals and kits are good) and cycling your water otherwise the tank type won’t matter.

-very loud air pump no matter what I do. -light is very bright and not really suited for plants -internal filter carts they want you to buy are a scam and expensive. filter Medium is too small, and doesn't really need to be replaced like they suggest. Same with the sponge, you can rinse your sponges/medium in aquarium water and get a lot of life our them. Just a huge waste of plastic if you follow their suggestion of buy new filters everytime and is also counter productive to keeping a cycle since new bacteria needs to be established. - internal filter idea is interesting but will consume and kill nano fish due to how the intake works. killed quite a few of my fish. - cleaning is a pain due to small lid - adding heaters or anything else looks bad since there is no extra holes. have to keep lid off or slightly off for space. - air intake tube for filter is at bottom of tank, when it inevitably fails it will leak everywhere. I finally managed to get it in a functionally better place after heavily modifying it but you loose the minimal look in the process. my mods are - - removing the internal filter entirely, its easy to do just remove some screws. using small plastic sheets and aquarium silicon I sealed up the hole. - made a custom laser cut lid that has mounts for a better light and holes for whatever (air tubes, heater cords etc) - added a basic filter, in my case a small sponge filter but anything would work. worked great once tank was cycled.

I see a lot of negative reviews about this tank, so I want to add a more balanced perspective for those considering buying this and housing a Betta inside. In summary, this is an incredible tank kit for those who take care of it properly. 1. Pump/air flow is too strong for a Betta. The pump has no adjustment so you will need an air control valve between the pump and air stone to tone down the flow. 2. Turn off the pump when feeding and simply drop your Betta food through the hole in the lid. 3. I purchased the Biorb Red Forest decor set which is intended for 4gal tanks, but found that I could only fit half of the items inside: the starfish, one tree, one short plant, and the "stone" centerpiece. More than this and the tank is way too crowded for a Betta to have a comfortable home, IMO. 4. You don't have to buy the Biorb filter replacements. You can find other compatible ones on Amazon for a quarter the price. It's just foam and carbon, you can even make your own if you're enterprising enough. 5. I have no issue with the LED light. Yes it's bright, but it scatters nicely over the bubbles, and because it's centered in the tank my Betta can just swim to a corner to avoid it if he wants. I think people are unreasonably concerned about this light. The MCR is nicer because of all the color options, but the LED is fine as is. 6. The pump I received with my Flow 15 is incredibly quiet when placed on a soft surface; in my case it's on a thin blanket that covers the top of my dresser where the aquarium sits. I barely hear it and it doesn't move. For those complaining about this pump, my guess is that it could possibly be an older model, defective, or on a surface that transmits vibrations loudly. I have never had a quieter pump before. 7. For those complaining about algae and excessive cleaning. This is never the result of the tank itself. It's 100% related to light and cleaning (or lack of). Don't put near direct sunlight, do 25% water changes weekly, and 50% water changes monthly. Regularly scrub the inside and replace filters. I mean, come on. It's an aquarium. You can't expect it to do everything for you. Rating a tank poorly because you're lazy at cleaning is ridiculous. Hopefully this helps other potential buyers who are considering buying this for a Betta tank. With the proper care (including initial cycling), additions (air control valve and tube guard), and practical decor, it can be a stunningly beautiful home for your Betta.

I love the look in the functionality of this fish tank. I really like that it has a light in a filter belt into it. Unfortunately, I hate that the lid doesn't come off and it makes it much harder to clean and I don't like that one side is rounded on the bottom so some stuff doesn't sit quite right on the bottom it's an all right material but the product is all in all all right. I do think that for the quality of the material it is pretty expensive. I thought I was getting something on the higher end for the price, but it is kind of typical it's just a more modern and sleek design, which is what you're paying the high price tag for not necessarily for anything special the filter is also stuck on, so I have not been able to rinse out the filter because I cannot get it apart. I've had to kind of flush it out instead, which is really inconvenient and very difficult.

Very easy to put together. Not very loud, almost gives a white noise kind of sound off. The only thing I don’t like is it’s hard to clean because the opening is very small.

It’s a very quiet tank and perfect size for beta fish. Works well and had good lighting and easy to clean

j'ai achete cet aquarium car je le trouvais tres beau seulement apres plusieurs tentatives avec plusieurs poissons de differents types, ca n'a jamais fonctionne... et c'est la que j'ai compris pourquoi il n'y avait jamais de poisson dedans dans les modeles d'exposition que l'on peut voir dans les magasins !!! La pompe de filtration est beaucoup trop forte et perturbe beaucoup trop les poissons. Les parroies font un effet miroir et ce n'est absolument pas adapte pour un combattant. Bref... passez votre chemin si vous voulez vraiment avoir un aquarium avec des poissons dedans.

I’ve been keeping fish for many years, mostly in more traditional glass, open-top aquariums that are heavily planted and require a fair amount of ongoing maintenance. While I’ve always enjoyed that side of the hobby, I was increasingly drawn to the design and simplicity of the Biorb range, which promises a more streamlined, almost plug-and-play experience. The FLOW 30 turned out to be an excellent choice, especially for a kitchen counter setup where space and aesthetics both matter. I’m genuinely pleased with how it looks and performs. The clarity of the acrylic is outstanding—it really gives a crisp, almost panoramic view of the tank that’s hard to match with standard glass aquariums. Setup was straightforward and quick, and ongoing maintenance is refreshingly simple compared to more traditional setups. That said, because the tank is made from acrylic, it’s worth being mindful that the material is softer and more prone to scratching. I’d strongly recommend using Biorb’s own cleaning pads or other suitable tools designed for acrylic, as these help prevent fine scratches and keep the tank looking its best over time. As with any aquarium, especially for those newer to the hobby, it’s important not to overlook the cycling process. Allowing the filtration system to establish properly is essential for maintaining a healthy environment for fish. Skipping this step can lead to avoidable issues and disappointment later on. Overall, I’m very happy with the tank. It combines style, ease of use, and quality in a way that makes it a great option for both beginners and experienced fish keepers looking for something a bit more convenient without sacrificing visual appeal.

luce hermoso en cualquier lugar.

Bardzo ładny

Je dispose déjà d'un biorb ou je rencontre aucun soucis, nous avons recu notre nouvelle aquarium ce Mercredi, zero soucis, aujourd'hui (2 jours après) le bulleur ne fonctionne plus, je met un avis négatifs car aucun service après ventre disponible via amazon sauf un retour produit, oui bien sur nous allons retourner le produit avec les 30 Litres d'eau + les poissons y compris la purge ... je trouve sa inadmissible de ne pas avoir possibilité d'échanger avec qq1 pour trouver une solution moins contraignante ...
