Hello. I just got the 300w (31") Viparspectra light. My tank is 75 gallon (48" long 18" deep 18"wide) I plan on setting it 8" high above the tank. I have a 6 month old tank with LPS, SPS and soft corals. What are the settings I should start out with as not to stress or kill anyone Plus how often do I raise/change the settings until I get desired results. If I left out any needed info...I apologize.
