I'm sorry, but someone saying "duh" doesn't constitue being rude and it's not worth getting my pants in a wad over. Again, it was not meant to be rude towards you so let it go Erik. It was more sarcasm about the TDS information related to proper fish keeping than anything else. If you aren't familiar with sarcasm or people joking around (which is very common on here as it's a very comfortable/open environment) then I'm afraid you will continue to be unhappy.

Again, let it go buddy. This thread has been side tracked enough and you already started your other little thread to make yourself feel better, so smile and have a great day.
