Seems that was a false alarm. He is happy and super big today. I think I just didn't know what his program is. The tank is 75 gallons with a 100 gallon sump/refugium. I checked the parameters. They were all good, did a water change just to be sure. I did re adjust my skimmer last week, and it took a little of my salt out. I put it back to where it was and slowly an bringing the salt back up. I think we are in the clear, just gonna watch it for a few days. Thanks for the help
