Black eggs in my macroalgae tank

[CringeTankDaddy]

What in the actual...is this? It looks like something bad but I just don't know. It's really creepy and gross. This was a simple low maintenance tank that was pure sunlight, with live sand, live rock, and chaeto. Feed it chaetogrow and about 2 weeks I see this stuff. Help. Idk if I can touch my water. lol.

Can’t see them in the pics… but based on your description, I suggest looking up bubble algae and see if that’s a match
