Well my tank has been up 5 months in 2 days time, i've got GHA and some briopsis and some beautiful red macro algae, different types, i've seen other tanks at 5 months and most of them had worse GHA then what i have, the same tanks at around 9 months are beautiful with little or no algae, so, my conclusion, ride out the storm without any drastic measures, stick to my filtration methods, don't confuse the tank by throwing various other forms of filtration at it and ultimately wait until my little micro bristle stars and asterinas and micro life that i may not have noticed is enough to eradicate the pest that is algae.
