I have a question about blue light

[Knight420]

I currently have a Fluval Evo 13.5 and wanted to add some more blue to the light. I have a few questions. I know a lot of coral really pops under more blue light. I just don't want to hurt anything by adding more blue to the light already provided

1. Will having blues affect the overall par level of the tank?
2. Will having the blues on all through the night have a negative effect?
3. If it doesn't affect much, can I have the blue on 24/7 and have the other lights on a timer?

Not sure about increasing par, but corals mainly use the blue spectrum to photosynthesize. So I don't think leaving blues on all night would be a good idea. They need time off.

Could I do the normal lights for 10 hours and just blues for like 2 hours? I'm more worried about raising the par in the tank too buch and burning the coral. I just want to add more blue for esthetics. Since they glow under blue lights

I think it would be fine, try and do it gradually.
