I have a 10 gallon QT tank for my corals. No fish. I have had some LPS in there for about a month and have put 2 sets of beginner acro frags in. One about 2 weeks ago, one a week ago. Everything was going fine until a hammer I had in there died (hadn't looked good since shipping) . I removed it when I saw it was dead.
I didn't think too much of it, but I have been watching the acros and a couple started to melt. I measured phosphate and it was at .29...way too high, I immediately did a 60% water change. Next day I came back and a couple more are not looking good. I did two water changes yesterday. And one today. I removed the acro that ended up dying and then clipped back the frags where they had melted. The majority of the frags are still fine. All the rest of the LPS is fine, but my phosphate keeps climbing right back up.
I measured at noon today after water change. It was at .16 ppm by 8 pm it was at .20 already. I have GFO in the canister filter and an extra pouch near a powerhead. I plan to do another water change and add some more GFO.
I don't know what else to do. Could the extreme phosphate level rise be all from dying coral? It is a small volume I guess.
1. Should I dip the coral? Coral Rx or Iodine?
2. Should I just risk it and put them in the DT so the volume dilutes it?
3. Should I just keep on the path and battle phosphates?
4. Could this be a disease?

Thanks for any help
