How do you fill your aquarium?

To fill your aquarium, start by placing a clean substrate at the bottom, if desired. Use a hose or a bucket to gently pour water into the tank, avoiding direct impact on the substrate to prevent disturbance. If you're using tap water, it's essential to treat it with a dechlorinator to remove harmful chemicals. Finally, ensure the temperature and pH are suitable for your aquatic life before introducing any fish or plants.
