Algae problems, Cyano or Diatoms?

[BubblesUp]

No other options worked for me so I went with the Chemi-clean. It worked and haven't had a problem since. It came in on a piece for me.

Well that's good to know. I have looked into chemi-clean but I don't think my problem is big enough yet to use it. If I can't keep it under control I may consider that option.

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
