Cyano or the start of coralline algae?

[Jasongtr]

For a few weeks maybe a month I've started to notice some reddish patches on the rocks, they started to be easy to blow off with a turkey baster, but now sometimes not so much, it does somewhat *but not all brush off with a stiff brush.

This is the interesting part, our lights right now are only on blues (it's the evening here) and I can see a fair bit more than I can when the whites are on.

I put the filters I have on my phone and it shows this.... it's far more in photos with the filters than I can see with my eyes, so do I have coralline starting or something far more sinister, theres nothing on the sand

Parameters are

Phosphate 0.07
Nitrate 12
Calcium 400
Kh 8
Ph 8.16

looks like cyano, could you send a picture in white light?

That's the thing, I couldn't see it in white light during the day, I will try tomorrow morning when they come back on

Or just red slime algae typically see in newer tanks started with fake rock.

Cyano isn't sinister, it's in virtually every body of water including our tanks. The key is to be patient and let the biome mature so that once the tank is stable, none of the nuisance algaes, etc, are out of control.

it does actually look more like red slime algae the more i look at it

Depending on the age of the tank fake rocks go through a variety of different colors as they mature.

Coralline shows up on plastic parts long before rocks in the tank.

Sounds fine in principle, but I guess it's knowing when to step in is the skill.

Just freaked me out seeing it a bit under blue lights then masses more with the filters on the camera when it's literally impossible to see when the white lights are on

Coralline doesn’t blow off at all.
A chisel maybe.
Cyano is not exclusive to new systems, it’s a triggered event.

You beat me to it!

So these are under whites.

The arrow in one I pointing to a snail with coralline on it so not part of the problem. As you can see nothing red is visible
