pink on rock

Coralline? Unusual color if so.

 

I'd say so, i have some pink and red, there's a lot of different colors of it, green purple etc

 

There are two spots of purple near by. These are the first few growths of Corralline in my tank that I know of. I noticed it when I moved the rock from the sand up to the top of the tank. Maybe I should move it back down. The little Coralline in my tank on frags has essentially bleached (think it's the 10000 k bulbs). hopefully it starts to take off.

 

You don't really have anything to stress with Coraline algae always a positive sign. Coraline is always a sign of a healthy system. I think the only down side would be that coraline uses calcium from your system but I am not sure if it would deplete your water of it.

 

Yeah, my second tank has been set up for a year, but has struggled to grow it. It adds great corporation to rocks, it's just a pain to remove from glass.

 

razor blade does wonders and if its bleaching its prob a cal issue or light issue

 

good news

I have pink, purple, Dark Red, Green, branching coraline and some thats so purple its almost black! very pretty when it covers the rocks

 

Yeah, these spots aren't, just the spots that came in on frags. My calc has been above 450 for months, but I just recently bumped up my mag from 900. I think my major issue is the stock 10000k .

 

prob

 

Between that and my blue + bulbs arriving this week, I'm excited.
