What is growing?

[BRB]

Anyone know what this is? Randomly started growing and i haven't added anything new in over 6 months.

Well, it's not SPS... it's Caulerpa racemosa. Macroalgae.

Looks like a grape calurpa of some sort maybe.

You might have real concerns if it "goes sexual" Here's an interesting perspective: http://forum.lionfishlair.com/marine-plants-macroalgae/is-your-macro-algae-about-to-go-sexual/

I'd remove ASAP as it can really take over a tank quick! If you can take the rock out and scrub it down well I would recommend it. You can place the algae in your sump for nutrient export. Just thin out as it grows.

Awesome i may try that, but just curious, what will it do if i left it and it took over the tank as you say? Will it kill anything or deplete certain nutrients or what will it cause or do?

It will shade and irritate corals. Once it gets a foot hold, it's near impossible to get under control as any little bit of tissue will regrow a new plant.

If you keep an ultra low nutrient level, you might be able to keep it in check, but it can be a serious problem if not as it grows very very quickly.

Interesting, thank you...
You think it'll effect anemones?

It can irritate them if it grows in dense around them, but most nems should be ok since they are big and thick skinned.

Unless you want a algae farm get rid of it. If you have a sump, put it in there and trim every month to export No3&Po4.
