This species of LPS will typically accept a wide variety of lighting. When first introduced though, best to shade it a bit so as not to cause light shock. You have it in a good place on the substrate but the depth of the 12 gal vs the light intensity will need some acclimation...Jermz79 said:48 watts of PC lighting
This is a concern, especially with an ailing coral. High Ca causes further stress and can promote polyp bailout if it gets much higher. If using a saltmix with that kind of chemistry, there's not much you can do but something you should consider changing. If the saltmix is closer to NSW, do a few water changes to get that closer to 410-420 ppmCal 465,
Good stuff... this type of coral will definately benefit from targeted feedings. It will also help the recovery process.At night all the polyps extend their feeders and look really good, I have fed them some Cyclop-eez and they go crazy ... gonna try some Mysis this weekend!
Even better news, this means that your tank is not the cause, you just need to tweek things a bit more optimally for it's recovery.I've had them now for about 4/5 days, when I got them they looked worse ... I told the guy at the LFS they were not doing good and I had a better home for them so he let me have them for $5bucks!!!
