Any thoughts on what these spots are? I'm guessing Lobophora. This is my first tank and my first run in with algae. I noticed the brown/tan spots/discoloration first. But tonight I noticed the black spots for the first time. I'm thinking it's lobo that hitchhiked in with my emerald crab. I also think his been picking it off and that may be the tan spots. Or it all may be lobo, or maybe something completely different. If I can see it so easily on the epoxy, I assume it's also all over the rock work. I read a post from another user who had success treating lobo with flucanozole. Considering treating before it gets out of control. Thoughts?

You can see both the light spots and dark spots have increased in size and number since these two photos were taken on Wednesday.

tested Nitrates and Phosphates. I was out of town last week and had an auto feeder set to feed 3 times daily so I thought I might have over fed the tank. Nitrate was at 14.4 ppm and Phosphate was 0.15 ppm. I had just done a 10% water change the day before.
