Instructions

    • 1

      When selecting an aquarium, keep in mind that there are a variety of shapes and sizes available. Choose an aquarium and stand that will fit the desired space and will blend nicely with your decor. Measure the space before purchasing it to be sure it will fit when you bring the aquarium home. Tank size will depend on how many fish you plan to have. A good rule to follow is one fish per one gallon of water.

      Choose a location away from direct sunlight, away from heat and air conditioning vents and close to an electrical outlet. Again, be sure to measure the chosen location before purchasing your aquarium.

    • 3

      Place the tank on the stand in the chosen location. Before placing anything in the tank, rinse everything with cold water. This will remove any impurities that may hurt your fish and pollute the tank water.

      Place the gravel in the tank. Gravel should be at least one to two inches deep. Secure rinsed plants and decorations in the gravel.

    • 5

      Attach the airstone to the plastic tubing. Insert the tubing into the air pump. Read and follow all air pump directions.

    • 6

      Fill the tank with distilled water or good quality drinking water. This is one of the main keys to starting a healthy aquarium.

    • 7

      Install the heater. Read and follow all directions for set up of your chosen heater. Most freshwater fish live comfortable in water that is between 70 and 80 degrees Fahrenheit.

      Read and follow directions to assemble the tank filter. Attach to tank and turn the filter on. Allow the aquarium water to filter for 24 to 48 hours. Check the water temperature and adjust the heater accordingly. When you are ready to stock the tank, buy fish from a reputable dealer. Slowly build up the number of fish in your tank. Adding too many fish at once will spike the nitrogen levels in the water and put fish under undue stress.

      When you bring your fish home, float the bag in your tank for about 30 minutes. This will help the new fish adjust to the temperature of your aquarium. After 30 minutes, open the bag. Scoop the fish out with your net and release into the tank. Do not pour store water into your tank. You have worked too hard to get the aquarium set up properly to let any amount of contamination enter the water.

      Feed the fish regularly; once daily or once every other day is plenty.
