Bright Green Spots on Pukani Rock?

[FishyReef]

Did a water change tonight and discovered that all of my pukani rock has areas that are turning bright green. It looks like someone dropped food coloring on it (and I know that didn't happen)! Anyone know what this is? It's only on my pukani rock, none of the others, and it doesn't appear to be algae (isn't raised or hairy). I have fish and a cuc arriving tomorrow and am hoping its not something horribly toxic!

That is really weird. Didn't happen with any of my pukani rock. Sorry I can't be of any help. Maybe try to Google it?

I had this on my rock before. I think I still might, too lazy to go check. I always thought it was encrusted green flake food. I do feed a lot of green formula 2 food. But maybe it's just some green coraline type algae. I don't think it's anything to worry about

looks like algae growth, normal stuff

Yup looks like algae...

Really, its algae? I believe you, I'm just surprised! It's so bright green, like magic marker green! I had no idea algae would be so bright!

It's algae. Could be the start of green coralline.
