Namyar sorry to hear your still battling. But don't give up or it will over take your tank.
For what its worth with my new tank I started seeing Algae appear then it came on rather quickly. I used all the suggestions that were given to you, Lawnmower Blenny, Tangs, and a GFO reactor along with manually pulling out the algae from the rocks and diligent weekly water changes. My tank came around very quickly. Heres hoping yours does as well. Good Luck..
