A nano aquarium is a smaller version of the traditional aquarium. It is a great choice for aquarists with limited space or budget. As a rule, these mini aquariums are smaller than 90 litres and offer an excellent opportunity to keep diverse aquarium inhabitants such as shrimps or snails.
Particularly well-known manufacturers of high-quality nano tanks are Dennerle with the Nano Cube, ADA with the iconic Mini M and Mini S aquaria, DOOA is known for the System AQUA. UNS also has high-quality nano aquariums in its portfolio with the 5N and 3N, which can be purchased in our online shop. The nano tank with 30 litres is particularly popular. This size hits the sweet spot between enough space to develop creative freedom, maintenance effort and purchase price.
However, if you want to buy an aquarium that has a small volume, you should be aware of some special requirements that need to be taken into account. Last but not least, it is important to create a healthy and life-friendly environment for aquarium plants. It is important to choose the right amount of inhabitants and aquatic plants to avoid overcrowding and the resulting imbalance. Special attention should therefore be paid to water quality. Water tests can help analyse an imbalance, and regular water changes are essential. Water conditioner can also help to create a balance. In any case, the use of our plant calculator is recommend.
Also essential is the supply of oxygen and a sufficiently dimensioned Filtration system, as a small volume of water can more quickly show poor water conditions. When buying a filter, it is important to consider that about 3 to 5 times the existing water column can be circulated per hour (e.g. 5 x 30 l = 150 l/h) in order to create a clean and healthy environment for the fauna and flora.
Another important consideration when setting up the aquarium is the Lighting. A nano aquarium needs enough powerful light, but not oversized lighting to prevent algae growth and promote plant growth. Dimmable lights that produce enough brightness to provide the aquarium with 25 to 50 lumens per litre are highly recommended. Furthermore, it is important to carefully monitor the light cycle to ensure that the animals and plants have a natural circadian rhythm. Constant, profound changes in lighting create unnecessary stress for the aquarium inhabitants and can lead to stunted growth and unnatural behaviour.
Overall, a nano aquarium is a great way to explore the world of aquatics without needing a big budget or a lot of space. The pocket-sized paradise fits on bookshelves, small cupboards or chests of drawers and also fits into life when space or time is limited. With carefully selected accessories and the right accessories, a vibrant and colourful mini ecosystem can be created in the home.
