Hi everyone I am hoping someone can help me. I have the deep maroon stuff growing all over my rocks and it hard tooth brush won't scrub it off.
I have seeded the tank with coralline algae from my old tanks. and I seeded heavily but i don't remember anything like this. As I went down from a 150 to a 57 That said I do have the pink coralline algae. This stuff I am unsure I covered the tank for three day and left lighting off. Today when I uncovered it it looks the same now I have very little green algae a couple of tuffs of hair algae. But hardly noticeable. You can barely can scrape with your fingernail but slippery as well. so any help would be appreciated
So here is a picture
Any help would be great it might be a type of Coralline i have not seen before. but the slickness of it makes me believe it might be something other than that.
OK Great as I have not seen this color before and it growth rate is very fast, This tank is shy of three months old. So I will continue then I guess. I do recall hearing this before but had not experience it so was doubtful of my own conclusion.
Just wondering~what type of lighting are you using?
+1 to this. As mentioned above there are many different forms of coraline algae which will flourish under different conditions. I also agree that this looks like a dark form of coraline to me as well. I'd just keep an eye on it as your rocks should vary in color as the become covered with coraline. At this point IMO I don't think you have anything to worry about.
