To help with your algae bloom I'd limit my light time. 6 hrs a day would be adequate.
Check a roony! Alk and Ca test kits, I'll have to wait on Mg until I get my first coral I think...er, probably just before I get my first coral.

Glenn, how many bulbs are you running again? When you say aqua blues I assume they are 50/50, atinics and 10k combo?
Since you don't have high light demand corals I would maybe go this route:
11:00am actinics
12pm act off/aqua blues
4pm act on/aqua blues off
5pm act off
Once you get more corals I would do your regimen that you have above.
Any lighting affects algae growth...Most likely its the aqua blues thats causing it.
