Not sure if this is going in the right place seeing as it could be a multitude of things but here it is. I have a kamry k100 and am havng multiple problems with all tanks. All kanger tanks work for about half a day and then I get little to no air through. I have tried multiple other tanks to no avail. Clearomizers all work great. Is there a reason tanks are not working or am I missing something. Have tried all the methods of fixing a pro tank and still doesn't work. Any help would be appreciated.
