1. Aquarium and Aquarium Materials
Thoroughly wash the aquarium gravel, rocks, and ornaments. Do not use soap or any detergents -- they are highly toxic to fish. To wash the gravel, put it in a plastic pan or bucket and add water. The gravel should be stirred and then drained. When the water stays clear after stirring and is free of debris, the gravel is clean.

2. Undergravel Filter (if used)
If an undergravel filter is used, place it on the bottom of the aquarium and cover it with two to three inches of washed gravel. Be careful not to pour sand into the filter stems. If you slope advertisement the gravel down toward the front, collecting accumulating debris will be easier.

3. Adding Water
Fill the aquarium half to three-quarters full. Pour the water onto a plate or into the cup of your hand so it will not disturb the gravel. To instantly neutralize gases such as chlorine, chloramine and flourine and heavy metals such as copper and iron, use a neutralizer such as ContraChlorine Plus. To remove toxic ammonia, chloramine and chlorine, use a water conditioner.

4. Connecting Air Lines
Connect the air line tubing from the air pump to any outlets inside the aquarium, such as undergravel filters, air stones or corner filters.

5. Decoration and Plants
Aquascape the aquarium with rocks, ornaments, and live or plastic plants. These should be arranged in such a way that the equipment will be concealed or at least will not detract from the appearance of the aquarium. If you are adding live plants, make sure that the water is warm enough for them. Remember to keep them moist from the time you buy them until they are planted. Plant the roots gently below the surface of the gravel, leaving the crown (if the plant has one) exposed, or they will not grow properly.

6. Adding the Rest of the Water
Fill the aquarium to near the top. Leave some air space between the water and the cover. Again, pour the water in such a way that you do not disturb your aquascaping and gravel.

7. Outside Filter, Thermostatic Heater and Thermometer
If you are using any outside filters, fill them with filter materials, locate them according to instructions and make certain their siphon is free of air. Secure the heater as directed, and place the thermometer as far away from the heater as possible. Make sure you can easily read the thermometer.

8. Starting Your Aquarium Equipment
Plug in your air pump, power filter and heater. Check the air outlets and adjust the settings. Make certain that water is flowing properly through your power filter. Adjust the thermostatic heater to the proper temperature, checking periodically. It will take some time for the temperature to stabilize, and you may have to adjust your setting.
