Think Setting up a Nano Aquarium is Hard? Think again.
This brings us to the point of size selection. We carry tanks as small as a half-gallon, although the more popular options start around 4 gallons and go up to about 40. Most hobbyists nowadays are using LEDs to illuminate their nano tanks because they are small and have low heat consumption. Another benefit is they last for years versus fluorescent and metal halide bulbs which need to be replaced every 9 -12 months. With the right type of LEDs, you will easily be able to produce enough light to grow corals plus you will experience their excellent shimmer effects.
As with all reef aquariums, water movement is important to keep your tank inhabitants happy and healthy. Small powerheads like the Hydor Koralia line, Tunze NanoStream and EcoTech MP10 work really well. Depending on the type of corals selected and the size of the pump chosen for the job, you may need one or two powerheads in the tank.
Selection of the livestock you place in your nano reef is vital to its success. Selecting appropriately sized fish such as a pair of Percula Clownfish or Gobies enables you to have movement in the tank while keeping the bio-load low. Coral selection is also important. Since you have limited space to work with, you will want to avoid highly aggressive corals such as Galaxea coral or some Euphylia corals. These corals have long sweeper tentacles that can harm nearby corals. Some excellent choices would be Leather corals, plate corals or xenia. You can see a wide selection or corals that MarineDepotLive carries.
As you can see, Nano reefing is not too different from larger setups. All that is needed is more attention to tank parameterssince fluctuations are more evident due to the volume of water or lack thereof.
