HELP!! whats growing on my SPS!!

[mpiton62]

Can someone tell me whats going on my SPS?

Am = 0
PH = 8.4
Nitrates = 0
Temp 78
Cal = 400
ALK = 9
Mg 1300

My yellow tang is also acting funny, not swimming around being very lazy.

I have a sps frag that has that stuff on it to but I haven't found a answer to it yet.

I would say that part of the coral is dead and algae is growing over it.

What can be done?

You'll have to find out what caused the stn. Have you dipped the coral? Is that part being shaded from light. I'd both those check out you might see if you had any major swings in the system.

Looks like algae grown on dead tissue, unless its a wide spread thing probably nothing to worry about.

It seems like the "brown" is going away slowly. I don't know what caused it.

I keep that SPS (i forgot the name, some kind of acro) in the middle of the tank with my AI sols. Anyone think it needs to move up to the top?
