It is a thin layer of green algae - not coralline. It is not a bad algae as long as you have snails and hermits eating it. If you do not like the pop - just suck it up with a tube but some hermits or sea cucumbers can fix it too

You made some smart decisions listening to reef2reef, tank looks like it’s progressing, I also don’t think that is coralline. Try blowing it off with a turkey baster and see if it comes off.

Have you seen a field that have been grazed by sheep or a lawn that has a robot lawnmower? If the snails haven´t done their job - it has been a hairy lawn.

Yea, coraline is good, it’s the purple stuff on most healthy reefs rocks covering them, like a candy shell. It’s like an apex rock algae, nuisance algae has a much more difficult time growing on it compared to just rock. So yea, it’s goodOh my goodness, now I don't know what to think haha, just wait it out right?![]()

I had mentioned to her about getting a small 75 GPD unit. No one told her to get a big unit.
Hi Guys, does anybody know what this green stuff is? Is it green coralline or bad algae? I got some turbo snails that removed the brown algae in two days, but whenever they go over the green rocks it doesn’t seem to be removing it, so I am guessing it is coralline. You guys are The experts so help please!!
Ps : I'm including a picture of Flash standing on the snails lol. He loves it. Also, these snails are a poop machine, it seems like the siphon DO NOT remove them as well. I tried picking them up with my hand, but the poop just dissolved lol. Does anybody know what can I do? It makes the tank look horrible.
