Hello Calvin,
The amount of time will depend on what you have in your aquarium. Also, the type of lighting you used before may be a factor. Generally, 6-8 hours of light is recommended, but some people run as little as 4-5 and up to 10-12. I hope this helps.

If you're switching to LED's for the first time, it helps to run them for 3-5 hours to start and possibly shade or dim the lights. This helps reduce the chances of shocking the coral. I hope this helps.
