I have had this tank setup for 2+ years and within the last 3-6 months I've been getting these weird white lines all over the glass. I leave the algae on the back glass because my CCS likes to munch on it from time to time and that's where these things are. There are like millions! They wipe off the other sides easily enough when I'm scrubbing algae. Any idea of what they are? I also have some live rock in there that it could have come from.
