Ok question...
I have ramped up to 60% intensity and 65% color from 45% intensity and 40% color over the last several months. It is 2-360s over a 21" deep tank...8" off the water line.
All seems to being doing very well but I noticed that my branching frogspawn and green nepthea seem to open up more at the 45% intensity and tends to expand out instead of up at 60% intensity. The both tend to be near the mid to top part of the tank.
I am wondering if it is okay to allow it more intense light at the peak time of day even if both corals seem to be their most expansive at 6pm in the day when it drops to 45% intensity? Is 45% too low of an intensity for the peak of the day?
It depends. If you want to add sps you may need a higher intensity and lower the corals you speak of in the tank. If you have pretty much just lps and softies and they are happy at 45% peak, then that's all you need.
