Does the RO unit you are getting have a DI stage? If not, I would add one. You are looking for 0 TDS ideally. Your algae could be hair algae or cyano from your description. I would siphon out as much as possible during water changes. Heavier skimming and more flow will also help.

The best thing you can do is eliminate the nutrients. Looks for sources of nitrates and phosphates in your filtration system. The tap water is an obvious one. Cut back on feeding as well.
