Looks like your usual cyano algae. It's very common for new aquariums, and almost unavoidable. Keep your lights off to get rid of it.

The solid dark piece looks like a sponge. Maybe a plating sponge.

Based off the age of the tank my actual guess is diatoms. They bloom right after cycle. Is it brown? It is hard to tell with the blue lighting

Welcome to the forum!
Another vote for diatoms. Unfortunately it will get worse before it gets better, but’s it’s all a part of the process. Good time to start building up your clean up crew.

Your tank does not have near enough algae at this stage to keep turbo snails alive long term

Please post pics under white light intensity. Very hard to accurately assess under blue lighting
