I just added my first acros to the top. Maybe 60% will be a good acclimation point to start for them.Well, they are low, but I don’t have diffusers specifically but 1/4” acrylic. And they are good for my corals as I don’t have any acros. Everything is happy and growing. At 80% at the top middle without the acrylic lid it was somewhere around 420.
Missed that third layer of control. Now I’m ramping up the lights over the next 4-5 weeks. Glad to have a workable solution, I’ve been pulling my hair out.
