Help with ID and Health

[jarrod0987]

Just got these the other day. Can someone help me ID the Branch coral please? He used to be brown but after 2 days turned light yellow. Is that good or is he bleaching?

Also the brains are browning out. Is that too much light or not enough?

I recently changed the carbon and have concerns about the temperature.
I was at 75 and they seemd fine. I let folks talk me into raising it to 80 and everything in the tank started to get bad. I am lowering it back down slowly now.

please help.

Tank is 10 Gal but only has 5 small frags in it.
Light is marine land reef capable LED light fixture.
Water parameters
Temp 78.3F
PH 8.1
Salinity 1.025
Alkalinity 11 dKH
Magnesium 1225ppm
Calcium 466 ppm
Nitrates .6 ppm (yes .6 not 6)

The first looks like it used to be an ORA Acropora of some kind.

The brain i would say Goniastrea http://coral.aims.gov.au/speciesPages/species_metadata/0193/view#

Thanks for your help so far. I noticed the rate of browning has decreased a bit. Also I see the brain had a few clear tenticles out after dark tonight. I believe this means he is hungry which i take to be a good sign. I may try some marine snow tommorow night after dark. Any idea if that Acropa turning yellow is a good thing or a bad thing?

The Acropora just looks like a stained skeleton, I don't see any tissue. If you see algae growing on it then you will know it is dead.

The Goni Brain will want something bigger to eat. When the tenticles come out try feeding brine, mysis, or chopped krill. Get it right in the polyps and let it close up around in it.
