Yeah, they don't seem to know much about the nitrogen cycle. All they want to do is sell the tank. They aren't in the business of keeping the fish alive. This site is wonderful for giving top notch advice to new fish people. Be sure to read the article here on the nitrogen cycle if you haven't already. Congratulations on the new tank.
