Pulsing Xenia Dying

[mechanic27]

Hi everyone. I am new to forums. I have a 46 gal reef tank. It has been set up for almost a year now. I have a marineland magnum350 filter, remora skimmer, 2 t5 aquatic life lights, do bi weekly 20% water changes. I bought the xenia as 2 small frags about 4 months ago. They were growing like wildfire. All of a sudden i notices them starting to look droopy. Within a few days they started dying off and floating in the tank. I have not used anything diffferent. I added a few new corals. I have had my lfs test my water and all my levels are good. I need help. Thanks

I heard that Xenia need iodine to grow and stay healthy have you tried putting iodine in the water?

xenia are vary sensitive to changes in water, id test your water to make sure somthing did't spike just to be safe

Can you please list you actual water parameters? And have you dosed anything in the tank lately?

I don't think you may have enough light in the tank..2 T-5 bulbs over a 46gal is kinda low. No need to dose anything in the tank, especially if you're not testing for it, just regular water changes will do.

MY ph is 8.4. Salinity 1.026, ammonia 0, nitrate 0, nitrite 0, calcuim 440,

I think they are dying from lack of light

I agree on not enough light.

I have that same light fixture on my 27g, it does give the option to connect up to 3 of them together so maybe you should consider adding another 2 bulb fixture at least.

be glad they are dying. but i do agree its not enough light

xenia is a very big plage one it starts you cant get rid of it

if you place the xenia's mid to top of the tank would that help?
