I did a ~40% water change today (First one in several months) to work on correcting my parameters. Anyway, when I did, I noticed my 2 corner sides are covered with a reddish/maroon/purple algae coating. As you can see in the pictures, it covers everywhere except where the powerheads were.
Any idea what it is? It is not coralline algae ( I have some on my overflow).
Also, any idea what all the white dots are?
