Looks good. That light should give you medium light anywhere from on top of the tank to 4 inches above the top of the tank.

are you injecting CO2?

people have the best chance of success with HC with a combination of High light and CO2 and a bit of luck. That can be a pretty difficult plant.

The T5HO is a very bright light for a tank as short as a 20L. You would need to raise the light 12 inches off the top of the tank to get to acceptable light levels. Otherwise you will fighting alot of algae.

You could get the dual t8, and then if you ever want to upgrade to higher light get a separate single T8 at that time.

A single T5HO might be suitable as well for higher light options.
This chart might help...
