Bryopsis removal

[Tangman]

I have a sea hare ( or had one. never saw it after add to tank, I have 300+ pounds of rock) but sea hares' are more parshall to Derbersia than Bryopsis.
I've been thinking of getting a rabbit fish but tangs wil not eat bryopsis even it starving, I should know ...I'm the Tangman LOL! Check out the avatar hes about 6 years old and 8 inches long
I'm also working on the nitrates and phosphates, even though my brand new salfert test kits read zero
