So I purchased this trachy about two months ago back when I was using a fluval Marine light. Now I'm using a AI prime 16hd and have obviously noticed all my corals liking the new light. In regards to my trachy I noticed before the switch that it was having some small areas that looked white. So I moved it from the bottom of my tank to the middle. After a couple of days since moving it I've noticed that it has started to "puff up". Is this normal behavior for being in a better spot or something else..
