Just a quick update. I really don't feel like getting onto dosing trace elements. I looked at my maintenance history on this tank and I've been somewhat lacking in my water changes and turns out I didn't even do one in December. Plan is to tighten up on those to 10% weekly. I did 10% Friday and another 10% Sunday. I also added some GAC and rowsphos in a reactor. I brought PO4 down from 0.8 to 0.4. which is where the tank has been running until recently so I'm ok with 0.4 Maybe the carbon will remove some nasties. A couple LPS are looking much happier and my zoas are perking up so hopefully sticking to the WC schedule will turn things around. If I do another ICP I'll report back. Thanks for everyone's assistance you folks are awesome.
