Plate coral not opening.

[tomjof]

I just got a plate coral on Thursday and I haven't seen it open up. Should I be worried. I haven't done a water test in a whole but I bought a Hollywood stunner the same time and it's doing great. It's orange with a green ring around it but it looks like it's bleaching a little close to the mouth. I moved it to lower light. What else should I do

I just did tonight and it looks a little better.

 

[jrjackson]

Okay, Im feeding it prawn eggs right now, should i feed it like mysis.

I know you said you haven't done a water test in a while, how about a water change?
I suggest you check all of your parameters and do something about the cyano on the sand-bed. At a minimum use a turkey baster and suck it out of there, it looks like it is starting to creep onto the coral.

I do five gallo water changes every week. I have a 30 gallon refugium on a 46 gallon bow front. I make sure the cyano doesn't go on the coral.

Cyano is a sign of high phosphate. I would do a 20 gallon water change with a gravel vac and vacuum the sand bed. Suck up as much cyano as you can because leaving it in the aquarium will only allow it to spread. What kind of lighting are you running? How many hours do you have them on for? Are you using a timer/controller?

I'm running a 120 w full spectrum led fixture with two 12 watt par 38 on the side.

And yes they're on a timer for about 8 hours
