Please help identify what's going on with my Favia and Candy Cane corals. Yesterday morning I did a water change, levels have been very consistent now for 3-4 months. I decided to go to my local coral supplier and pick up some new coral for the tank. I picked up a Favia (Green with white centers), Candy Cane (lime green), Indophyllia, and a few Rhodactis mushrooms to add to my tank that has only housed a Zoa, GSP and a Goniopora. Zoa, GSP and Goni have all been doing great. I started asking the guy at the store about dipping corals, and he recommended ReVive Coral Cleaner for 15 minutes, than a quick splash in H202 then right into the tank. Thats what i did, and the Rhodactis, and Indophyllia did just fine however the Favia and Candy Cane do not look very good. for what its worth, i did also add another piece of dry life rock after rinsing in RO water. I woke up this morning and both the Favia and Candy Cane look really bad and has white slimy substance coming off of it, and the brown appears to be flaking/falling off too. I used a small turkey baster to suck the white slime off. i tested my levels, and my Ammonia spiked to .50ppm, Nitrate was at 5.0ppm Phosphate, PH, Alk, Nitrite, and Calcium are all stable like they have been. My normal levels are below. Can anyone please help out with a few items. 1) lighting program Photo attached (this is not a preset, its just what i had been running with Zoa's GSP and Goni and was working well.) Photos of corals attached as well, and up for suggestions on anything that i may have done wrong and how to (if i even need to) help keep these corals alive. I did a 25% water this afternoon to help reduce the Ammonia and Nitrate.
