I have a Photon V2+ 48" that will be going over my 120 gallon. The current plan is for the tank to be a mixed reef. With the upper portion for SPS and low in the tank for LPS and other lower light things. Does this schedule seem to be reasonable?
1- Definitely start lower and work up to those.
2- The V2+ controller ramps for you, so a three hour ramp up is good, but do keep in mind you can ramp up a bit faster, the light changes 10x an hour, so you don't need to fill it in as much as the original V2.
