How long does it take to see results? 

This largely depends on your light / CO2 levels as these are the main determinants of growth speed in the tank.

If fast growing plants have been facing nutrient deficiencies, dosing APT produces dramatically quick effects within days - deeper reds, greener greens and new shoots should be well formed.

In slow growing low tech tanks, the impact can take several weeks, as the rate of change is very slow. The benefit of APT for slower growing non-CO2 tanks is that old growth lasts longer, and stays healthier. Healthier plants are more algae resistant.
