Green Coralline Algae?

[gummi]

My tanks is about 6 weeks old. Past the diatom stage...

My live rock is starting to turn a bit green in spots and the purple coralline is growing slowly as well. The green parts are not slimy at all and can't be scraped off with a toothbrush. Could these green patches be green coralline algae?

Any way of getting it to go more purple than green?

There is a green form of coraline. It generally turns pink/purple after a while. It's not clear whether the green turns pink or whether a pink form outcompetes the green.

Wait a while, and it will be pink.

My tank is also new and producing - I suspect - the same thing yours is. I too am waiting to see what color it ends up.

My rocks too turned green. It was a beautiful color and I wish some of them stayed that color. After about a week they began turning pink and eventually purple.

The same thing happened in my tank. It didn't last too long. All of the green eventually turned purple.

is there a preference between these colors?

there was some green coraline on some of the LR I picked up the other day, it's nice looking stuff. I also wish it could stick around and coexist with the purple stuff.

I think both colors are nice though the corals stand out more against the green rock. If I had a choice I would probably go for the green since you don't see it. It's more of a shiny pastel color. Here's a shot of what it looks like. Again, mine is now purple.

Mine is not that green. Light green. Purple is more desired because I think green has a negative connotation as it is often the colour of nuissance alagae

I always want what I can't have. So I have a ton of purple and pink...now I want green!
