This is my build - have brown powdery algae on my rocks and a little forwards the bottom of my back panel which I assume are diatomes.
Have some bright green patches starting to get slowly grow over them.
Is this cyano?
Also, what are the tiny white/purple spots asserting to form on my highest rock?
