Many, welcome to the board. Good to have more Vic people on here.

Hair algae is often caused by too many nutrients. This means too much food going in, not enough water changes, and/or too small of a skimmer. It can also be caused by too many fish, and IMO, you have enough fish now. Adding more will cause more algae problems.
First thing I would do is get rid of the cannister filter. You don't need it with all that rock (which is your filter) and you can put the money towards a better skimmer. The remora pro does get good reviews.
Have you thought of adding a sump? It might make selecting a skimmer easier, it would add water volume and give you more things to play with.

As for lighting, you'll at least need VHO tubes for LPS to thrive (or equivalent PCs). You could also go with 175w MH.
Hair algae is sometimes blamed on old bulbs, how old are yours?
