Macro consists of nutrients the plants require in relative abundance. They are generally prevalent in tap water and should not be added to the tank as they will likely produce algal blooms. Micro nutrients are those required in trace amounts, many can actually be toxic at high levels. These are generally not available in many city water supplies or precipitate out easily. If you phone your city you should be able to get a copy of tests done on your water supply. To send these for analysis would be fairly expensive, for not much benefit. Generally, I only add micro-nutrients during a water change if the plants have started to look a little brown or lost some of their colour.
