I have an aspire BDC tank. I have had it for almost a year now. And just recently my liquid has been leaking through my coil and is getting on the screw in part of the battery. Do I need to change tanks? I have replaced my coils and nothing works. I have been having to keep q-tips on my to clean the battery. Is there any tricks I can do to stop this from happening or like I said just end up changing the tank?
