Euphylia coral won’t open?

[John A!10]

It is soon going to be the second week that my grape coral hasn’t open.
I will post my parameters later, and pictures when the lights are on.
Any ideas why?

What type of flow do u have it in

 

[Cory]

Check for any stray amperage.

What do you mean. My other corals are fine.

It’s pretty much a goner, I tried in many areas of the tank still nothing.

Get a multimeter, set it to milliamps. And see if it reads anything. One probe in the water and one probe in the ground prong of the wall receptacle. But best look up testing for stray voltage, but also test for amperage as thats the killer more so than voltage. It happens when your equipment has micro leaks.
