Last night I was doing general maintenance, changed about 10% water. Everything for parameters looked fine. I added this odd light fixture that is a 19 watt T6 and 19 watt T6 actinic just to add some actinic light and a little brightness to my tank. This is a stop-gap measure until my replacement 2x39 watt T5 is ready. I have 2 stalks of pulsing Xenia and two heads of ricordia that are about 8 inches from the surface. After coming home from work, I noticed one of the Ricordia is shriveled up and looks terrible, and one of the stalks of Xenia has a branch that looks white and shriveled like stump. The other Ricordia and Xenia are perfect. I am not sure if the added light would be enough to do that, my first thought, but then I realized that I had been cleaning off salt creep and I wondered if perhaps a couple pieces of salt might have fell into the tank and landed on these corals. The fact that one is fine and the other is damaged makes me think the salt did it.
salt or light problem?
