Algae Growth On Glass

[Jeremy Lain]

Hello, I am cycling my tank and I am now getting some algae growth on the glass. Is this the same thing as diatoms? Or maybe the beginning of coralline algae? Should I clean it off the glass or leave it? I will attach a picture.

diatoms

leave it or scrape it.... it will go away in time
