Hello from Vancouver Island been analog free for 12 days now and thanks to this site, it has helped me find a setup that works for me. Spinner 1300 and a t3s tank and 3 diffrent juices for around 50 bucks and I am pretty happy saving 80 bucks after 2 weeks. Now my question I noticed in the last 2 days I have to use pliers to undo my tank and the threads have blackened. Is this normal or am I making it to tight etc ?
