Ok so I got the aerotank about a month ago loved it, phenomenal. Now it's giving me trouble. I started getting a burnt taste and less vapor production, I tried soaking the parts in vinegars few hours then a hot water wash and dry burn. The horrid taste would subside some then return. So I replace the coils and it works great but a matter of days later it's back. I use a 50/50 blend I know with burnt taste to adjust the voltage but my battery doesn't adjust voltage I unscrewed it slightly to reduce the heat. I can't be replacing coils every few days I have the parts on a 24 hour soak in vinegar I am using a back up ce5. Any other ideas?
