How long to light acclimate my tank?

[NeveSSL]

Hi guys!

I have a new retrofit kit coming in from ReefGeek on Thursday. I'm planning on using eggcrate on the top of my tank and putting pieces of screen on top and taking one off every once in a while.

My problem is that I'm not sure how many pieces to start with and how often to take one off. Any ideas?

I'm going from NO to T5HOs, FWIW. Quite a jump.

Thanks!
