I'd be interested in knowing about all of the different color forms of coralline algae.
Recently I've had two major changes to the system. I added a large number of snails which I purchased online but caused my tank to be on the verge of crashing because of a 90% mortality rate. (Still fighiting with vendor on that one) I've also added about 5lbs of garf grunge which introduced additional flora and fauna.
During the recovery of my tank, my purple coralline algae has started to die back a bit, with a big circle of it in the middle of the tank turning white. Once things settled, I've now seen what looks to be a really pale green coralline algae. Its definitely not "green algae". Its growing in calcerous circular patterns like the purple coralline does.
I'm wondering if this green coralline algae is from the garf grunge or the existing coralline being stressed from the sudden tank rebound.
