All In One Nano Reef Tanks For Beginners


As mentioned in the article Saltwater tanks for beginners, that sometimes a larger saltwater aquarium can be more forgiving and easier to maintain. While that is true, I know many beginner hobbyists plan on starting with a nano tank. There are so many different styles of aquariums available on the market today. Pretty much anything you can imagine is out there, and if it isn’t, you can have it custom made. The nice thing about having an all in one tank, is they are basically plug and play systems. So if you are a beginner or even an advanced reefkeeper, an all in one tank might be the perfect fit for you. In this article, I will show you the best all in one nano reef tanks that are great for beginners.


What is a nano reef tank?


When I first started in the saltwater hobby, I heard a lot about nano tanks but had no idea what they were. Basically a nano tank is just a compact or small tank that is usually less than 30 gallons. It’s for people who may have limited space to keep a larger tank but still want to set up a reef aquarium. The nice thing about nano tanks is that they can pretty much fit anywhere and don’t require custom-built heavy-duty stands for them. A basic desk or table will often be all that is needed. Smaller reef tanks are visually stunning, and with some creativity, you can build an awesome little reef tank. Some people will keep nano tanks in their office or bedrooms and others will use them as a showpiece in their main living space. Nano tanks are easy to transport and not such a big deal when they have to be moved.


Are nano reef tanks hard to keep?


I wouldn’t say that nano reef tanks are hard to keep, but they do require lots of attention and proper care. Smaller tanks can be less forgiving with respect to water quality and can be more challenging to maintain. As with any aquarium setup, planning ahead is important and learning as much information as you can prior to setting up can save headaches afterward. Of course, you may make mistakes along the way but that is expected. Just learn from them and move on. If you take things slow with a nano tank, things should work out just fine.



Advantages of a nano reef tank


So we already know that nano reef tanks can be a bit less forgiving than larger tanks. But they do have some advantages.

  • Cheaper to set up and operate
  • Take up less space
  • Easier to move
  • All in one tanks are plug and play
  • More energy efficient
  • Don’t require external equipment and plumbing


What is an all in one tank?


An all in one aquarium is a complete packaged aquarium system. Basically, when you buy an all in one tank, you are getting supplied with everything you need to set up and operate right away. The aquarium will come with a built-in filter system, filter padding or sponges, bio media, return pump, and some even have a canopy with built-in lighting. The only thing you will need to add is a heater if it’s required. All in one tanks are very modern in design, don’t require additional equipment to hang on the back, they are affordable, and don’t need any extra customization. They are ready to operate out of the box.

The new design has built-in LEDs under the hood which are controllable with moonlights and timers. The built-in filtration section can be used for any filter media you choose. If you decide to build a refugium in the center section, Coralife was smart enough to have a clear panel on the back of the tank to incorporate light for any macroalgae you want to grow. This set also has an optional matching stand, which of course I had to have!
