What is Needed for a Nano Aquarium?

  1. Filtering

The filter is an important part of nano tank equipment because it can keep the water properly clean and provide water flow in the tank. If the tank is not equipped with a filter, do not worry because it can use a hang-on-back system that functions the same as a filter in general but it uses mechanical, biological and chemical. At present, many nano aquariums are equipped with a small inbuilt filtration unit at the rear.

  1. Heating

The intended heater is for the maintenance of tropical fish that needs to maintain a consistent temperature in the water. Some heaters can be adjusted in temperature and make it possible to control the temperature of the water and keep it stable to find the optimal temperature for most tropical fish. Because the temperature of the water can support the fish to be inside even though the fish itself can regulate its own body.

  1. Lighting

Nano aquarium lights are needed to make fish appear brighter and provide enough light to see if there are problems with fish. At present, many tanks have built-in lights free of charge, but sometimes there are some tanks that are required for personal purchase or additional lighting. The lights are enabled by most fish species to help mimic the natural cycle of day and night. In addition, the lights themselves are needed for plant growth that is placed in a nano tank.

  1. Nano Planting Tank

Most suitable for planted aquariums are soil-like media. However, the equipment needed for a nano aquarium will largely depend on the type of tank desired. Because it might be possible to choose to maintain freshwater or saltwater settings. All of that, back again to the desired species such as tropical fish or cold water, which might require heating.

How to Set a Nano Tank so that it runs well?

Nano fish tank is very easy to install if the equipment is complete. It is better if there is a manual available for Nano Tank settings that can be followed. Following are the steps to ensure preparation of the Nano Tank so that it runs well:

  1. Choose a location to put it in the right place to start it. Avoid natural light sources to prevent the development of algae and from other heat sources.
  2. Perform routine tank cleaning, both new tanks always do the cleaning to remove dust. For cleaning, you can use warm water or vinegar to make it more sterile.
  3. Add pebbles, sand or decorations as desired.
  4. Place the heater and filter, installation of tanks for saltwater requires additional protein skimmers and powerheads.
  5. Prepare water suitable for storage for freshwater or saltwater. Make sure you use reverse osmosis water, or remove chlorine, and add salt if you install a nano reef tank.
  6. Place a small bowl on the sand, as a place to pour water up so as not to move the substrate into the tank.
  7. The tank needs to complete the nitrogen cycle, which allows beneficial bacteria to build up and help convert ammonia and nitrites which are lethal to fish.
  8. Enter the fish species and give them time to adjust, provided they are not included immediately. Let them float in their bags in for 10 minutes, and then every five minutes, add a cup of tank water until the bag is full. Then can release the fish into the tank.

When deciding what type of arrangement to use, it is important to consider the needs of the fish you want to maintain. The best bet is when adjusting the tank around the species all in one aquarium. The advantage of a larger tank is actually easier to maintain in the long run. Plus giving you more room for fish and plants. However, the space needed requires a large space too. In contrast, a nano tank that requires little space. It’s easy to see why nano tanks are so popular. Because this tank is pretty and compact enough to meet many different budgets and life situations. So many fun and creative things that can be done with smaller tanks.
