I put Chaeto in my refugium about 3-4 weeks ago. It doesnt seem to be growing too much and its definitely night in a real tight ball either. Actually wasnt when I bought it either. It gets about 14 hours of light a day and I try to flip it a few times a week as its not tumbling. Everytime I flip it it sheds a lot of strands. Does this mean its dying? It looks to be a really nice bright green and very healthy but why is it shedding so much? Maybe I should try trimming it? Its actually a good size piece right now.
