How long after setting up the aquarium should I wait before adding fish?
If you have thoroughly rinsed all non-electrical parts of your aquarium, as well as your gravel and ornamentation, fill your tank with water and aerate it a few days (or a week if you have the patience). By allowing the water to stabilize, you reduce the stress on the new fishes. In fact, most pet and aquarium specialty dealers will test your water as a service to their customers to ensure a balanced tank. It is our strongest recommendation that you follow their advice; their expertise will provide you with invaluable information and assistance along the way. Additionally, there are easy-to-understand books available at most pet stores that will answer most of your questions. You will be anxious to introduce fish to your new aquarium, but first be sure that the environment you have created is a healthy one for them.
