algae help please

[uads]

I have discovered an algae growing in my tank that i can't identify readily. I think it might be brown slime algae, but it doesn't have the same appearance as I have seen in my research on line. Can anyone assist me in this identifiction? My tank parameters are Salinity 1.024, pH 8.3, Mg 1100 (low i know, but i am bringing it up slowly), Kh 6.4, Ca 415, NH4<.25, NO2 0, No3 0, PO4 0, temp between 78 and 82 depending on how hot the peninsula is that day.

Thanks in advance.
