Lighting

If you have the lights at about 7 to 8 inches from the water would having the blues at 80% be to intense I have the whites at 40% I've noticed that my star polyp has bleached a little

Try to put down ur blue at 70% and white at 35% and see what happen and if it doesn't work then just play with it!!

That is pretty intense. Coral bleaching is a good indication. Always always always start low and raise slowly.

Well I did give them the acclimation cycle but all you hear is ramp up your blues but I started thinking maybe if you had your lights at 12 inches or higher I don't think any t5s have the actinic at 80% intensity at least that's what am seeing corals that use to be real Green are now getting a little brown

I've been running my Black Box blues at 55% max, whites at 10% for two years, 11" from waters surface.
Start asking "they" if they're using a par meter or their eyes to set intensity.

These guys are resilient at a lot of lighting intensities
Also a huge indicator of water chemistry

*they are the eyes of my tank*

And a Lux meter is cheap. it measures intensity.

Try to put down ur blue at 70% and white at 35%

Then youll know 70% of what. And go up or down from there.
