Cyano dino or both?

So my new 14g biocube is about 2 and a half months old at this point. I noticed a slight cyano outbreak it has escalated to a brown stringy slime and a red film covering rocks. This let to me removing the sand bed. My nutrience isnt bottomed out its sitting around 10 ppm nitrate and .05 phosphate. The red film is for sure cyano but I am unsure what these brown strings are. They don't have bubbles or anything like dino.

It may just be diatoms. Kind of hard to see it being stringy in the pics.

Now that I google it. Diatoms may be what it is.
