I have a 4 bulb t5 HO
over a 20l. It was doing great in the tank I had it in before upgrading to the current. I acclimated it over an hour replacing small amounts of water with a turkey baster from the new tank. I dipped it in a 10% peroxide bath for a few minutes just about an hour ago and there was done brown stuff coming off. I just hope I can save it, it was my first coral and was doing so great! Here is a pic after the dip... If looks soooo pissed. Any other suggestions? I also spot fed with microvert after the dip.
