Hi Cameron, I do have algae, just in different forms than most. I have red turf algae and dictyota, although my blonde naso destroyed the dictyota and I don't see it anymore.
I actually enjoy the red turf algae and let it grow. The tangs and angels pick on it and it's a healthy absorber of nitrates and phosphates.
But, to get to the source of it all, I control the amount of algae by controlling the nutrient levels. I haven't been able to keep up with your build but I just remember last that you were dealing with hair algae. I believe I may have mentioned that your amount of live stock in your tank might be a bit too much and more importantly, you introduced them too quickly. Quickly meaning that systems need time to adjust to larger, messier eating fish like tangs and angels. They have a huge biological impact on your tank. If you add multiple ones in a short span of time without allowing your system to adjust, then you'll just have an excess of nutrients.
If you catch yourself in this situation already, frequent water changes are ideal until your system can stabilize as well as frequent manual removal of the offending algae. Adding other pathways of nutrient reduction well help too, such as a refugium it reactors (biopellets, GFO, etc).
