Features to look for in a small desktop aquarium kit

  • Size: The first consideration is size. Make sure the dimensions of the aquarium match the location where you want to place the tank. Be aware that water weighs about nine pounds per gallon. A three-gallon aquarium will weigh at least 30 pounds in addition to the weight of the gravel, ornaments, filter and light. Be sure the location where you plan to set-up the aquarium will be able to safely support it.
  • Filter: Your aquarium will need a filtration system to keep the water clean and clear. Most nano and smaller aquarium kits include a built-in filter. A submersible water pump circulates water through the filter media and back into the aquarium. The filter also provides water circulation that helps oxygenate the water
  • Heater: Freshwater tropical fish, marine fish and reef invertebrates require warm water with a stable water temperature. A heater will prevent the water temperature from falling too low. While goldfish thrive in cooler water, it’s a good idea to use a heater to reduce water temperature fluctuations. You may have to purchase a separate aquarium heater if the kit does not include one.
  • Lighting: Aquarium lighting will show-off the fish’s beautiful colors. It also highlights the aquarium gravel and ornaments. If you plan on keeping marine invertebrates like corals, you’ll need brighter “reef lighting.” Most live aquarium plants don’t like dim light. Look for an aquarium kit that comes with more than a minimal lighting system. Today’s aquarium kits almost always use modern LED lighting technology. LEDs run cooler use less energy and last for many years. The other benefit is that LED aquarium lighting can be customized for reef tanks containing corals and live freshwater plants.
  • Gravel and ornaments: Most aquarium kits don’t come with gravel and ornaments. That’s OK because it allows you the fun of selecting the color and type of gravel you want. There are also thousands of plants and ornaments to choose from, so you’ll be able to create a truly one-of-a-kind aquarium!
