Removing phosphates. Suggestions?

After 3 years of using tap water on my aquarium, I know it's finally time to change up to RODI.

Some of the things I noticed

1) A large green algae spot growing behind the rock work
2) Green algae starting to grown on the sand bed
3) Decrease growth in corals

My question is where to start?

- Should I replace the sand bed since it is now showing algae growth?
- Should I removed the large algae spot behind the rock work, or let it continue to bind phosphates until it starves off?
- Lastly, should I do a massive water change or continue on with 15% every 2 weeks?
