What is this sheeting red stuff?

[MTBake]

Any ideas what this stuff is(see pic below)? I've dealt with cyano in past tanks and none of that looked quite like this. It pretty much disappears overnight and has regrown within a couple hours of lights on. Anyway, an id would be awesome so I can deal with it accordingly. Tank is 1 year old in 2 weeks.

Parameters;
No3 10ppm salifert
P04 .016ppm Hanna ulr
Ca 430ppm salifert
Alk 8.3dkh hanna
Mag 1230 salifert
Temp 77-78
34ppt salinity

Here's a couple pics;

Yeah I went through the same thing with my tank. It will pass, keep up with your water changes. Watch how much you feed your tank. Also how’s the flow in your tank?

Looks to me like Red slime algae, but not entirely sure from your photos.
One thing I would do, would be to raise your magnesium levels! Seems to be a little low.
I found that quite high mag levels help combat nuisance algae. Mag level up to 1350+ but that's just my opinion.

Thanks everyone!

Kinda figured that's what it was. I've never seen it so thick. Going to keep siphoning it out with water changes.

I was actually going to raise the mg level as well. Seemed kinda low to me.

Yep raise the mag levels! And I forgot to mention like you said siphon out as much as poss! And water changes!
