I'm going on about month 6 of slowly losing most of my LPS and SPS to tissue recession. My 70G tank has been set up for a year (was a migration from an established smaller tank), and I've frustratingly been unable to add any new coral as they just tend to die.
In my acros its showed up as discoloration mostly starting at the base, sometimes mesenterial filaments with some bleached tips, then frequently they STN or RTN after a while. Some montis and other encrusting SPS seem like their tissue slowly thins over a period of weeks-months. In fleshy LPS, they start receding at the edges with skeleton showing and over time disappear. I've lost 5 acan colonies and 4 micro/favia colonies to this. A few smaller zoa colonies have disappeared over time as well.
For a time I was convinced it was pods, and this is still my best guess. I don't have any amphipods from what I can see but have a ton of munnid isopods that I see on the corals at night. They seem to be eating or at least irritating corals but I've never heard of pods killing acros so I'm still skeptical on this. I added a small mandarin a few months ago, who is fat and happy but doesn't seem to be helping. I've been trying to get a leopard wrasse from my LFS for months.
Am I on track thinking it might be pods, or is there some other potential cause I'm missing? None of my other fish or inverts could be causing this as far as I know. Light is an Orphek Atlantik so should be plenty. Water chemistry has been in line, ICP test a few months ago came back with nothing out of whack and I've got a second one in the mail right now.
PLEASE HELP! I'm going crazy from this.
Parameters:
Alk 8.0
CA 420
MG 1440
SG 1.026
Temp 79
NO3 1
PO4 0.1 (high I know, previously though this was undetectable and I had to dose to keep it off 0. I was having these issues with 0 P04 and NO3 and thought they might be due to low nutrients).
