Looks like a marine filament fungus. You could try MelaFix, safe to treat the whole tank.
Try and get you lvl's up a little and your salinity down 1.035 is high for that and I didn't see what your Mag. Was try and dose to get those up a little there is a great video on you tube that shows you how to figure out exactly how much to dose I'll fine the link and post it .....I have a 75 gallon reef tank with 30 gallon sump. I been battling "whatever this is" for a while now and I'm just not getting anywhere. From my research it appears to be what others have referred to as "white slime" and is a bacteria. I don't get algae on my glass. I get a white film that covers it. It also covers my rocks if I don't siphon it often
I have tried scrubbing it off the rocks and doing water changes, running gfo, ran a UV sterilizer. Tried dosing vineager (made it worse).
Tank parameters:
Alk 8.5
Ca: 405
Sal: 35
Phosphate: 0 (hannah checker) assume it is being consumed by bacteria so it is showing 0
Did not have a nitrate test kit..
I have been battling it almost since I have had the tank set up which is 1.5 years....
Any ideas or help would be greatly appreciated!!
