Lighting changes

I have a Nuvo 20 with one kessil 160we, it's not nearly enough light for this tank so this week I finally ponied up and ordered a second one. My question is I'm running the single light at 75% about 10 hours a day, when I put the second one on can I run them both at 75% right off the bat or do I need to start them lower and acclimate the corals to more light?

I would start them lower, and slowly raise them over a few days.

Also, buy or rent a par meter. It's all just guess work otherwise. I thought I had an idea of what I was doing until I got one and realized that I was about 50-75 par lower than I thought I was.

I would love to rent one, I just keep finding it at the bottom of my priority list. Maybe I'll rent one now so I can better position the lights and intensity.

It was a real game changer for me. You may also look into local reefing facebook groups. Now that I bought mine, I'll loan it out to others on the groups sometimes.
