Good morning just opened my Red Aspire Nautilus 2 tank. All excited to use it and sadly the airflow was off of the tank. The rest of the tank is fine, just assembling this airflow ring is exhausting as I don't want to harm my tank. I own 4 others and have bought them for friends and family. I CANNOT find anywhere on the forums how to re-attach the airflow to the bottom base. Any help would be greatly appreciated!
