BMW: I wish I could say that I was surprised by that reaction, but this type of comment is why so many people get turned off to this forum and to the hobby. You know nothing about me, my situation, or my tanks. So, if you don't think something is right, or are concerned about something, then voice your opinion or ask a question without being a jerk. Otherwise keep your mouth shut. I thought these kinds of things were taught in kindergarten. Guess you missed the lesson.
