I am not sure if this is a coincidence or not but I just did a 25% water change and used a new salt. A few days later I have this CRAZY outbreak of burgundy red 'VERY HAIRY" algea. Nothing like I have seen before. Usually I have cyno but its more of a flat covering.. this stuff is like strings trying to grow up.. only on the crushed coral/sand base! The salt was Coralife Marine Salt Mix. I also vacuumed the bed pretty good. Up until this I havent had any problems Please help. I turned the lights off in the tank, but overnight it doubled in growth!
