Rock Turning Green?

Diabolic · 03/11/2010, 06:37 PM

I first want to start off my saying how much I love my marco rocks. I have noticed over the past month my white rocks have slowly been turning green. I don't think it's a big deal as I've seen it happening with other peoples marco rocks in the picture thread.

My question is, what is it? Is it green coralline?

too many nutrients?

Skimming?

Water changes?

Over feeding?

Nitrate / Phosphate?

Thanks for the response.

too many nutrients? (I don't know. I'm new to this hobby so I'm not exactly sure what that means.)

Skimming? (Yes. There is one built into my 34 RSM 130, although it isn't that great)

Water changes? (I do a 4g water change every weekend)

Over feeding? (I doubt it. I just got my first two fish last weekend)

Nitrate / Phosphate? (both read 0)

I wish I could take a photo but the color isn't coming out correctly on my iPhone. It's a neon green color like the examples below:

mine looked the same at first, it eventually turns to purple (normally), I wish part of its stayed that lime green color. Coraline algae can be different colors, especially at first, but eventually it usually turns purple/pink.

it's a natural process, your rock will eventually turn purple, give it time.

Mine is doing the same thing.

Thanks all. I figured it was normal since I've seen it with others. I was hoping to find out if it indeed is green coralline or something else. I see a bunch of pink/purple/red coralline starting to cover the rocks, so I'm sure in a few months it will be covered.
