I'm setting up my 75 gallon tank tomorrow using the same method I did with this tank.
I'm using this method because I've seen SCMurphy use it in several tanks with great success. All of his tanks seem to go through this initial bloom just as mine has so I'm not terribly worried. Also, this tank will be running UV sterilization as it is in the living room and I can't afford a green water period this time.
I'll also be using milder lighting as well so we'll see if those two things make a difference.
