Xenia and cloves are very similar but the xenia will pulse. Both are moody corals
See the directions on the marine snow and do about half what they suggest. Slowly build up. I've never used that product so not sure on how it performs. I do know that SPS will benefit from dosing things like that, in addition to good lighting.
A lot of people have luck with just doing weekly water changes with their sps tanks. Do you have test kits for Ca, mg, etc? You can see how much your corals utilize to determine if you will need to dose.
Well then I believe I have xenia and cloves! The pulsing ones weren't in the tank yet when I took that photo.
I used marine snow the first time I had this tank set up a couple years ago and it seemed to do well for the corals. You do need to feed corals planktonic food, right? Did I just make up a word?
I do not have any of those advanced test kits yet. But they are on my ever growing list of things to buy.
