So I just corrected a medium sized hair algae outbreak in my tank, all clear now. With that said this may have been there before but, I think its new within the last three days or so. The algae has been gone for about a week and I don't remember noticing it when it cleared (I was doing plenty of looking at my once again clear rock too haha). It is like a red stain on the rock that does not appear to have any texture per say (if so very thin). I wouldn't think it would be coralline because of the color and I have not seen any in my tank up to this point with the exception, I did notice some on my crab's shells recently (though that is the purple).
I will attach a photo of what I am talking about, my apologies for the blues, though it does not wash out the color of the rock stain that I am reef-erring to (so that is the color I see). It is the large almost streak on the rock farthest forward in the picture. You can also see it in the rock in the back (just to the right of the hammer). These are the only two spots in the tank that it is present. Any help identifying this is appreciated! I don't think it is a big deal but would like to learn and know.
Tank Parameters at last testing (4 - 5 days ago):
Salinity: 1.026
Temp: 80
Ammonia: 0
PH: 7.8 - 8.0 Color is kind of between the two and hard to tell for sure
Nitrites: 0
Nitrates: 5
Magnesium: 1260
Calcium: 420
Alk: 9dKh (not sure why it is much higher than "normal." test before about 5 days before was 8 - 8.5)
I am not dosing anything at the moment because there has not been a need. Water changes keep them up.
