I fought a desperate battle with GHA when starting my 120. It was bad, real bad! I tried several chemical manipulation tricks and critters ( note: Lettuce Nudis don't mix well with VorTechs .... Yuk!). You do need to stabilize nutrient import/export and water params (pH, Alk, & Mg seem most important to me) to stop the GHA growth, but if it's bad and thick already you need a serious appetite for algae to clean up the tank.
What did the trick in culling the GHA was a Sea Hare. The only problem is, you need to monitor the Sea Hare as it is a giant shelless slug and if it dies in your system it could reek havoc. Once the GHA is gone, you need to pass it to another reefer or return it to an LFS as it won't last long without a mass of algae to eat. And they eat a ton of algae very quickly! It will eat everything off rocks, sand, glass,and equipment, and is large enough to handle the big flow you have.
