I have a 30 gallon tank and just started adding corals into it. After adding a silver Xenia mushrooms and a Christmas favia my ammonia levels are up to 4.0 and my pH is at 7.4. My silver Xenia has been shriveled up for 24 hrs now and doesn't look promising. I've been adding ammo lock but my ammonia has been on the rise. And the favia looks alittle faded in color. Any suggestions?I added a picture of the Xenia and favia. Thanks for your help
