800 gph, depending on how the flow is broadcasted and broken up by region, can be a lot for a 30 gallon.
is my open brain coral dead?

Corals with skeletons like that: (open brains, acans, plates..etc) can easily be damaged by too much flow.
That being said, lots of shrimp if not getting fed enough will come and eat LPS corals...and for some reason they like to target the species listed above. I have an acan colony that gets eaten/cuts itself on its skeleton all the time. Goes down to almost nothing like pufferpunk says, and then in a couple weeks you will see a couple little patches starting to come back.
Have patience, and be careful. If you have moonlights, keep a lookout for nighttime marauders.

that is my concern. maybe i should turn the wavemaker back on. will cut down on flow 250gph. and if i need more flow i can use the vortech.
here is how the flow is now. both the internal pump are on all the time now. i face them straight and towards the surface. they are located on the back top.
the vorteck is located on the left rear about 5" down from the top . it blows current around the back of the rocks from left to right. it isnt directly blowing on any corals but as it came around the rocks it would directly cause more flow on the brain coral and the frogspawn.

I would think the frogspawn would go because of flow issues well before the brain, that being said, the could both get beat up, especially by direct and or laminar flow.
I suspect sand damage or your mantis...
