I'm loosing the war with GHA, help?!

Sorry if I missed it, but where exactly is the algea growing?

Is it on the rocks, the sand?

Is it possible that where it grows, there is an excess of nutrients?

Could the live rock or sand be leaching nutrients?

Something has to be fueling it's growth.

Could you pull out the rock and put them in a quarantine tank? Where does the algae grow then?
