I had a kengeer tank that was leaking so i bought a new zephyrus v2 firs time when i filled it up its was leaking a little bit. Second time i took it all apart to make sure that everything is tightened and filled the tank again but forgot to close airflow holes so i tought that might be the reason why its leaking. Today i noticed that little air bubbles comming from bottom to top inside my tank and its leaking. What im doing wrong? Its a brand new tank got it just yesterday. Please help and thank you
