I setup my tanks how I like them from the start. I do this because I don't like to mess with the tank after setup other than weekly maintenance. I am still learning about what plants are good for certain setups and occasionally pull out bad plants, but I am doing this far less as I gain experience. I have also learned how to keep algae down after setup by just not dosing ferts. I dose after a certain amount of time, usually 2-3 weeks. All of this is from experience though. I have one of Amano's books, and he explains that while his tanks look great now, he has made many many mistakes. He even says he has made some mistakes multiple times. Experience is very important in this hobby and helps us make good decisions. Telling a newbie to use stems to absorb nutrients is probably best, because they might not know what else to do. They will learn though and make better decisions the next time around.
