Beginnings of coralline algae?

[LOVEROCK]

I have the same question: is this the start of coraline algae?

Looks like it

No one guess cyano?

He said it wouldn't blow off and had to be scraped so not cyano.

It looks like the beginning so might not blow off too easy...
also that's all relative to someone new to the hobby...

As others mentioned, it typically appears on plastic parts long before rocks.

Yeah, it's the plastic I'm talking about. The purple on the rocks in the background is Caribsea paint.

You will know for sure soon enough

His rocks will change a variety of colors as they mature. Mine still do. The urchins strip parts white, then various film algae covers them again which the starfish likes then eventually coralline returns and the urchins repeat the process.

Hey guys, it's my first time starting a tank with dry rock. Tank it's about 2.5 months old, stocked with fish, no corals. I haven't rushed the corals because I have other tanks to hold them until i feel like this one is ready, i haven't tested parameters but I'll run an API nitrate test for **** and giggles, i see between 5 and 10 ppm. Salinity is .026. does this look like coralline growth to you? It only grows outside of direct light, does not baste off and i have to scratch it with a fingernail to get it to lighten up. I seeded with snails that have a bunch on Thier shells.

This is a translucent coloration. Coralline is more opaque. This might be cyanobacteria.

Unfortunately that looks like the start of Cyanobacteria

could you confirm your parameters nitrates, phosphates and could you double check salinity?

Yup
