Hello!!
I've noticed some white stringy like stuff that has been growing on the live rock I bought from JL and lately has spread to some of the dry rock I cycled as well. Some of the older strands have slowly turned a brown colour but were white/beige for a long time.
The pic shows some newer growth on a small piece of rock from JL. Is it just a harmless bacteria growth that will subside or could it be the start of some nuisance algae?
It's not all over the place but I do see more of it sprouting up.
I have blue legged and Scarlet hermits but they seem to ignore it. My cerith, astrea and trochus snails seem to ignore it as well. Bio-load is fairly small with just the cleanup crew listed, scarlet shrimp and a purple firefish at this point.
