Just to give a little info to the dechlorinator/no dechlorinator debate going on here;

As far as water testing, once you get a little more knowledgable about fish behavior, you can tell if something is a little off, this is when I will do water tests. I have many tanks that have never been tested, and others that haven't been tested for many months.
As far as for a beginner, I would advise water testing and dechlorinator. Once you get a handle on fish behavior and such, you can ease off on the weekly water tests that would be wise for a beginner to do. As far as dechlorinator, and the explaination in that link, I do at least 50% water changes on my tanks, and the amount of ammonia produced could lead to problems, especially for fry, which are more fragile. No doubt my bio filtration would take care of it in time, but in that time damage could occur. I acually worry more about heavy metals with adults than chlorine/chloramine/ammonia, so use a water conditioner that had EDTA.
Mr. Rush; (I really like that one!) while I do agree with many of your ideas and methods for more advanced aquarists, and I do practice several that you mentioned, I would not suggest them for beginners. It is best to start slow with anything, this includes aquatics. I would hate to see a newbie crash & burn without a viable backup plan or the know how to pull it off.
When you have your first lesson in driver's ed, you don't get pointed down the expressway on ramp during rush hour, and when you are trying to teach a kid to ride a bike you don't yank off the training wheels and shove them down a half pipe. Many of the things you advise are fine for advanced aquarists, who have experience, spare tanks, and such to recover if there is a problem.
