Algae problems, Cyano or Diatoms?

[GoFish]

I never had cyano until using Phosphate Solution (Precision solutions) to lower phosphate. It worked great but then got Cyano for the first time... Used chemiclean as directed and the cyano disappeared within 3 days and hasn't come back
I can't tell from your pictures if it's cyano, just saying if it is +1 to chemiclean
