Anyone please tell me what this is?

This is all over most my rock, snails and on frag plugs a bit. I brush with a toothbrush and it's gone, but then back.
Testing water is all normal. Any ideas?

Sounds like Red canyo. Gone in the morning and back strong after a day in the lights?

It's not red if that matters? What is red canyo?

What color is it? The images are hard to see on my phone.

Is it a brown slime? If so could be dinoflagellates (dinos).
There is a great thread by the member twillard about getting rid of dinos.

It is a dark greenish type, but not slime. More like fuzz!

 

[reeferfoxx]

Maybe spirulina?

@twilliard can help :)

It's algae
Now let's keep this in mind..
A person can chase no3 and po4 all day long and not win the battle. Why a person askes??
Photosynthesis
This is how they can survive while the person is scratching their head.

Odd what species of Sally is it? It doesn't have any yellow and red does it?
