I will only be keeping LPS corals for a while as I gain knowledge for SPS. I have 2 AI prime 16 HD lights and I have them on a 9 hour schedule. My PEAK lighting is a 4 hour period but even then I have no lights over 50%. One- Is my lighting sufficient and two- should I lengthen, shorten or leave at 9 hours? Thanks for the help in advance!
