salinity spiked to 1.029 from 1.024

asterina star? or your salinity at 1.023 and the spikes at 1.025?

zoanthids need a lot of stability in alkalinity and salinity otherwise they will melt. So you should get your parameters stable and your zoanthids will not melt any longer. Even a very small shift in alkalinity can make a colony melt. I had this problem before I got my dosing pump but since I got my dosing pump my alkalinity stay stable as a rock and no more zoanthids have melted for the last 2 months.

I recommend not adding any coral until full research. Xenia can be a weed and as you add coral you want... The Xenia may over grow it.

Patience and diligence = success.

Keep your system simple... At least at first... And as your knowledge grows so will your tank.

Enjoy.
