Help with ID

Hello! Recently got a microscope to help identify a few things and finding it difficult to know differences of things I’m seeing. Here are a few videos and pictures of what I’m seeing.

I'm no algae identification expert but I think you should break up/dilute the sample so we can see individual cells clearer. Also include magnification so we have an idea of scale.
