Basically the adjustable airflow valve thing on my delta 2 coil is loose. Everytime I go to fill my tank I notice that the airflow valve on the coil is closed which is odd because I always leave it open. I do notice the adjustable valve seems a bit loose I am not sure. Has anyone had this problem or know what might be wrong? Should I just pick up a new coil? Honestly the Delta 2 annoys me so much, however the thing is durable all hell and the glass is not all that exposed which is why it is my subtank of choice.
