Howdy, need help ID'ing this red/maroon algae-like stuff that grows VERY quickly all day long, then literally disappears at night, and starts up again the next day. I can practically see it growing. It comes off rocks and gravel really easily, but it'll come right back in a few days. Sometimes it'll have bubbles in it, especially on the rock. Tank is about a year old, NO3 and PO4 are near zero most of the time, other parameters are pretty normal.
Just curious what it is / if it's something to worry about?
Thanks in advance!
