Description

You'll find the biOrb FLOW 15 Aquarium is a really easy aquarium to set up and own. Everything you need to start your aquarium is included in the box. It uses the proven biOrb filtration system and also has a built-in LED light. The biOrb FLOW 15 is ideal for keeping small fish or shrimp and is compact enough to place on your desk or in a small space. Most aquariums use small box filters and/or smooth gravel which easily clog with dirt. Like all biOrbs, the biOrb FLOW 15 uses special ceramic media to provide biological filtration, which has a surface area equivalent to the size of a soccer field. Any excess waste is collected and held in a filter cartridge at the base of the biOrb. To maintain your biOrb FLOW 15 all you do is simply replace the filter cartridge every four weeks and change a third of the water. For safety and peace of mind, the lights and air pump are low voltage. The aquarium itself is made from acrylic. You can enjoy all the technology of an advanced aquarium set up, supplied in one box, making the biOrb FLOW 15 Aquarium the perfect aquarium for anyone new to fish keeping.

  • I’m honestly undecided.
Size: 8 Gallon Style: LED Lighting Color: White
This tank is absolutely beautiful, hands down my favorite design, however I may have got myself in a money pit. Not just the tank itself, but everything you need to go with it. I had read the specs several times before committing to the purchase so when I got it home and started reading, I wasn’t able to use the sand I purchased, as well as the air bubbler, and automatic fish feeder. I would have saved my money on those products if the manual was included in the specs. Also, you are required to use the specific filter for this tank and change them every 4-6 weeks and they are pricey as hell. It also says in the manual that there are other pieces that have to be replaced after a year and I’m sure they are a pretty penny too. Like I said, I love the design of this tank so I’m going to try to troop through it, but if I would have known this before I had to get the physical tank in my possession I may have considered another alternative. I will include manual in my review. Hope it helps! ... show more

  • Low Maintenance High Relaxation
Size: 4 Gallon Style: LED Lighting Color: White
I Love the style and design of what Oase Living Water have to offer in the BiOrb aquarium collections. This is my first BiOrb FLOW tank. And my first Betta! ( always had mostly schooling fish when I was a kid). Set up was super easy. Just follow the simple step by step pictures. I purchased several different plant accessories instead of a Decor Kit so that I can have a more customized look. Once set up, the water has to Cycle for 24 hours so don’t go to aquarium store to get your new fish until the BiOrb is ready . I decided to get a Betta because the Petco Fish expert said my 5 gallon tank isn’t big enough for anything else. (I didn’t want a goldfish because I know the filter would need to be changed more frequently). This is the way a Betta should live! He seems So much happier than in a bowl of still water. The pump runs hard so it bounces right off the table and just continues to do so. It’s long enough to reach the carpet from the tv console table the tank sits on, so I wrapped a sock sound it (as another buyer stated) and you can barely hear it if it’s up against the wall ;) So fast forward to my first Complete water change... yes I had to do a complete water & filter change after just 4 months because the instructions on the Aqueon betta food say to feed 2-3 times per day enough that could be consumed in 2minutes. Algae started growing on everything so I added a few cherry shrimp to do some cleaning up. (Shrimp are the only other aquatic species that the Betta won’t kill). I went back to Petco to see if there was some kind of drops to quicken the algae kill, and when the Fish Chick seen my picture she said my Betta is Bloated and she shouldn’t be able to see the fish’s waste. So over feeding caused the rampant algae growth and since I had large white rocks in the front and the ceramic media toward the back, you could actually see how much Brixton was doing his thing if you know what I mean, so I chose to start over~ fresh. I removed the large topiary ball because it was taking up too much space. Brixton is now on an more appropriate diet if just 3 tiny nuggets of food once a day. I will update went it’s time to do a Partial water & filter change, ;) ... show more

  • Beware-- may be dangerous to Plecos :(
Size: 8 Gallon Style: MCR Lighting Color: White
Just bought this beautiful tank for my beloved Beta fish 'Moonie' and blue-eyed, albino Pleco 'Sunny'. Poor Sunny was killed by this tank because I turned the center air tube off overnight due to the fact that it is too turbulent for my Beta fish. Sunny crawled into the tube overnight and couldn't get out. I found Sunny dead in the tube this morning.. While this tank is beautiful, easy to set up, and seems fairly simple to clean, it is also very turbulent for Betas so I have to turn the air off to feed my Beta and give him a little rest. Be careful if you have a Pleco and you turn the air tube off. I don't want anyone else to lose their fun loving Pleco to this tank like I did.. ... show more

Size: 8 Gallon Style: LED Lighting Color: Black
I've been waiting to write a review until after a few months of use. 1) I was concerned the substrate would be too hard for my fish, but they've been fine. The amount of substrate included doesn't quite cover the filter but it doesn't bother me. If you're unhappy with the substrate you can always buy a cheap substitute. 2) The opening to the aquarium is smaller, but cleaning hasn't been difficult. 3) I was disappointed the light is very bright and doesn't have brightness settings. The chord pops out prominently from the top, and I wish it was more conspicuous and build into the tank. Additionally, for my tank environment, the light gets covered in algae and requires regular cleaning. 3) The equipment for the aquarium isn't that expensive, especially if you buy something compatible that isn't biOrb brand. Overall I would recommend the tank, especially if you enjoy the design like I do. ... show more

  • Stylish and functional - love this tank!
Size: 8 Gallon Style: LED Lighting Color: White
This tank is gorgeous!! Super easy to set up, and this is my first tank. Yes, it's a bit pricey, especially if you add all the Biorb decor..but I think it's well worth the money! Our little betta is so happy in this tank. Also, I've seen a lot of videos online of people overstocking their 8 gal Biorb tanks with fish. Please do not do this! Do your research before buying a tank and fish! Just because it's 8 gal does not mean you can stuff 20 fish into it. We have one betta fish in our 8 gal, and she is so happy! Please read the instructions that it's a 6 fish max tank; 6 small fish! But we (and more importantly our betta) love this tank! ... show more
