Bubba you should find another home for your tang but it is up to you to keep what you have or not. I am sure you have heard already all the reasons why. However, please don't suggest to others here to emulate your set up. No, you didn’t directly do that, but by describing your set up with the PBT the “suggestion” is there; even if unwittingly. While it is up to you to what you want with your 20gal tank and your PBT, your setup should not be something that new, unknowledgeable hobbyists be encouraged to follow. On the other hand, I can’t imagine that sarcastic remarks about hobbyist doing something wrong is going to help them change their minds.
When such happens, I can only think that the more knowledgeable individual is more interested in pointing out bad judgment, rather than attempting to help or advise. On the other hand, hobbyists who continue to make the same mistakes, even after being advised over and over of wrong-doing, are likely to get some heat. Just keep in mind that when the flames start up, even when someone is WRONG, that is a reflection on you and this BB. Someone new to the forums may see your sarcastic or nasty remarks to someone else, and not know the history, thus come to the conclusion that this place is unfriendly. Just keep it in mind that when you speak here, it is public speaking, not a private conversation.
Also, bubba, its not against the rules to quote a mod per say.
