I had this algae a couple of years ago and it was a tough one. I 
tried everything, trimming back the affected parts, reduced lighting, 
reduced fertilizer etc.. It flourished and the plants didn't. I then tried, 
which felt wrong at the time, to feed the plants which would starve 
the algae by competing for the nutrients. I started to fertilize 
normally and took cuttings from my hygro and planted it throughout 
the tank. Several weeks later, after the hygro had really started to 
grow, the algae started to turn white, from the top of the tank first 
to the bottom later. In about 3 weeks the algae was gone and has 
never returned. I hope this might give you some clues on how your 
staghorn might be eliminated.

BTW, no fish touched the algae and I had Oto's, SAE's and
