White Spots on Zoas

[AlohaKai]

Hi. I bought these bam bams from a local reefer 2 days ago. They were not like this when I brought them home, and they definitely weren’t like this in his frag tank. The lights are barely coming on, otherwise they all fully open up and seem happy. It’s definitely not sand. My other zoas are spot free, including the other frags I bought. I’ve never had issues when purchasing from him—I don’t even find pests after I dip, and everything opens rather quickly. Would this be zoa pox or do those typically appear on just the stalk? First pic is from minutes ago, second pic is under more blues and taken almost 24 hrs ago—you can see the spots appearing on one zoa. Thanks in advance for the advice!

Here are my parameters. Ph was 8.2 last night and temp has since increased to 78.2°. I have moved them into quarantine until I figure this out. Thanks again!

Here they are today, still in quarantine. I think they look better.
