Diatoms turning yellow

[neoh74]

Has anyone experienced the diatoms turning yellow during cycling process? Partially cured live rock was added with marine land m2 media with a dose of live bacteria. It's been a week and just last night my brown diatoms turned yellow.

Not diatoms.. Likely the start of green film/hair algae

Thank you. I haven't seen this the past cycles I've done. Prob happened at night when I wasn't watching.
