You should really use RODI water if possible for your reef tank. Not as important for a FOWLR but you don't really know what TDS are in your water from the tap. You can get a number but never know what is really in the water. If you're insistent on Tap water you need to find the right salt that has lower MG and things in it that you are too high in your Tap water. If you want to use the better light switch to it and just start it off low and work your way up over a couple of weeks. Have you fed the anemone at all? Does it have a good food response?
