Light Acclimation or not?

[125mph]

I read that sometimes you acclimate coral placement and slowly move it up more and more. But why is this?

I also noticed most LFS run very low intensity lights when they sell the frags in the frag tanks. Is there a reason for this? And is that why when you bring home the frag you should light acclimate?

Never done it.

Corals don't have big increases in light very well so it's a good idea to do so if this scenario applies to you.

If the lights are dim in the store and you have 600 par, you can/will burn that frag.
