It depends on the coral and the strip. You need 450nm (blue) light for a lot of the photosynthetic corals. There are a numbr of corals the do not need much light however, but those require more frequent feeding.
What LED strip? Just saying it's an LED strip is like saying yeah, I have a car. You have no idea what kind, what features it has, whether it's right for the application, etc.
Those are a pretty terrible light to start with, but you don't want one that only has royal blue LEDs. Only fluorescent colors (which are almost all green) will be excited by blue light - all other colors will not show up at all.
