My prime led has a acclimation feature Im only running at 50% for the red white and uv the rest run at 80% peak time so what ins a good rule of thumb time period for the the acclimation like 30 days or fifteen days ?
Slower is better, in my opinion. Gives you time to observe your corals while they adapt to your new light. Also gives you an opportunity to make adjustments before you burn a coral and kill it.
My 2 cents
