Over a month have past since the last update, so here it goes.
1stly the hair algae : I think the war is over and we have won. Kept the lights off for about a week, and since then we've only kept on the 3Watt blues and been feeding 1 frozen cube per day instead of 2. Will probably begin increasing the main lights slowly this week.
2ndly, no new fish or coral added but everything doing great, especially the shrooms, which are growing very fast.
