coralline algae quick question.

[danschargers21]

I have a bunch of rock that was taking from an established reef. I let it dry in the sun for over a month, and bleached. I cured it for a week when I was ready to start the cycle on my tank. The rock had a bunch of what I thought was dead coralline algae on it (mostly red).
When I added the rock I also added 2 new pieces of dry rock to the tank. Its been about 2 weeks and I have noticed little red spots of coralline algae on my new pieces of rock. Does coralline algae not die? Will it start to grow again so I wont have to add any pieces of live rock to get coralline algae on my rock?

Thanks guys!

its only sustainable in a mature tank

Coraline algae absolutely does die and a lot quicker than a month. Sounds like you'll have fun trying to figure out where it came from. Hehe.

Sounds like you're not shooting for much biodiversity, eh?

No way it could have made it through a bleaching IMHO.

I have noticed saltwater organisms of all kinds are very resilent and not as sensitive as thought. It's amazing how you may have assumed that all was dead , but it is possible that deep within the rock there was enough of a pocket or trap for some to stay alive.

The other question i have is , Are you sure it's corraline algae and not cyano?
