Default Is this black fungi and how to treat it?

Greetings All,

I need some help here..i am not sure what is this..i highlighted it in the red box...it is spreading to all the roots. I applied some fungicides as well as hydrogen peroxide but i am unable to get rid of it.

I grow some of my orchids in leca...even some leca balls have them.

Can anyone advise on this?

Thanks

This is algae or blue-green algae, cyanobacteria. It does not harm the plant.

Yes. Very common in high humidity.

Hi Estacion,

Noted. Thanks for the advice. I thought it was some fungus and is sucking the life out of my plant. I tried so many ways to get rid of it but is so difficult to get rid of it. I even consider cutting all the affected roots and repot my orchid.

Thank you very much.
