Is this Algae good or Bad?

Is this Algae good or Bad? Do I need to check any parameters?

What are we looking at? All I am seeing is a clean tank.

Are you showing the "dust" algae on the glass or the color of the rock?

Both are normal, what is on the rock is good. What is on the glass typically gets cleaned every few days by most of us.

Don't see anything growing in the rocks? Give us a closer view. Are those rocks real or fake

 

[BeeReef]

Thanks for the response.
They are Real rocks , the rocks were green sometime back, now reddish in color. wondering if its bad algae.

Do you have any pictures of when it was green?

 

[BeeReef]

no

Do you have any pictures of when it was green?

It was green right after the nitrogen cycle completed.

I was just wondering what it looked like. This is what mine looks like just after the cycle.

I could see the dark brown thing falling off one day, I took a turkey blaster and cleaned the rock. a brown layer blew away and settled on the sand bed.
and revealed the rock. see pic. is this cyanobacteria? i have a PO4 as 0.5 ppm from Hanna checker.
