Mirror Mirror On the Wall, What's the Color Of It All?

[talenzmeier]

Ok, so this is a newbie question. I have a newly establish marine tank. It is fish only and it has a 75 gallon capacity. The nitrites have just finished dropping to normal levels. For the past several weeks we have been seeing a fair amount of rust colored "stuff" on the bottom of the tank and on the ornaments. We assume that it's algae (the tank has been running for 6 weeks). Lately, we have a new color showing up. It's an irredescent pink! Can I assume this is algae too? If so, any cause for concern? I know marine tanks take a long time to completely cycle, hence my reason for asking. Thanks!

Do you have lr? The pink algae could be coralline (sp?) algae. This is usually a desired algae.

No, I do not have live rock.

The rust color is most likely algae. what did you use to fill p your tank? If it was tap water, that is most likely the cause of it. Using RO/DI water for water changes should clear it up over the course of a few changes. Not sure about the pink stuff but im sure someone in here will tell you what it is!

you will get a variety of algaes that will come and go as your tank cycles. You said your nitrites have "droped to normal levels" what are the levels? You're shooting for 0 nitrItes.

Normal Nitrites

They were at 0 until I added two Chromises. The NI are elevated slightly at the present moment.
