How to cultivate those nice red coloration on live rocks?

[cutebarra77]

I saw some reefers' live rocks have this red /purple coloration and look awesome.

I'm not sure if the red coloration on live rocks are algae, but they certainly do not look like it.

Is there a way we can cultivate that?

anyways, what are those red coloration?

There r a couple of U-Tube videos on how to do it. Just watch n follow. It's that simple.

Enjoy.

Is it coralline algae? It forms naturally in tanks with time....

You are probably referring to coralline algae. Some have had success with the Purple Up product. your rocks need to be free from other less-desirable algae in order for coralline to set a foot hold. so keeping water conditions good will be helpful.

lately have been staring at the red coralline and starts to suspect if it is cyno

use chopstick to rub it but it seems hard....

Yes. This is the type of purple 'pigment' I'm referring to. The red stuff is another.

Reefers,

thanks for the inputs and you people were right.

The algae I'm referring too is indeed red and purple coralline algae.

And yes, tons of resources in YouTube on growing them.

Many thanks. Time to take some action now.
