For sure use RO from the start and save the headache of algae blooms. Cycle, cycle and cycle some more-in the dark. At least 6+ weeks with no water changes. Make sure everything is how you want it. Get a refractometer and good test kits. Research and decide EXACTLY what type of fish/corals you want (will they be compatable, cost factor and care requirements) and what you want your tank to become in a years time.
You are on the right path-patience and research.
