Welcome!!!
I had lived many, many years ago on Maui! probably the best years of my life.
I am unfamiliar with the BioCube lighting but there are options existing to change out. I would only do so when needed.
The best advice I can give any new reefer is to go slow. Sounds like a nice, long, slow, cycle already. While your tank may appear cycled it may not be sufficiently populated with the beneficial bacteria needed to support life unless you have been feeding your bacteria population the whole time your tank has been fallow. Make sure that you have a proper bacteria population before adding any life, coral or fish. Start here and read.
