so today i received some mail it was my mini protank 2. i went to clean it out...let everything sit and dry...and as im putting everything back together i notice the coil wont screw into the base. so i did some research just to make sure i was doing it right..it just wouldn't screw in at all.. i look inside the base and there are no threads to screw the coil
. what do i do? email the company i got it from or kangertech? any info would be greatly appreciated
