Alright, so I have a tank, approximately 1 1/2 years old.
Tank was doing phenomenal, growth, stability, everything you could ask for.
Then, almost like a soft slow crash, with tank wide coral by coral STN.
Parameters do not fluctuate. 8.2dKH, 410cal, 1400-1420 mag as of today. Parameters were the same as time of "crash" (which is still ongoing), tank is setup with auto doser dosing ESV.
Now the tank is a LPS dominant tank. And I have ALWAYS dealt with low nutrients (think undetectable but without Dinos).
I have tried to rule out everything. I have moved coral to a different tank after dipping and debriding with lugols and dipped with Coral Rx. Neither show any change and progressed in a different tank (also low nutrients its common across all my tanks). Checked tank for copper with Hanna. Tried carbon to pull out any possible contaminants. I have tried almost every possible thing, to the point where all I have left to do is
1. Get an ICP (currently doing)
2. Bring up nutrient levels with heavier feeding, no skimming, and dosing neo-nitro/neo-phos as well as occasional amino (also currently doing).
I did check a few pumps, and I added some poly-filter today to check for metals. But I dont believe it to be a contamination issue, as I have feather dusters blooming like crazy in my sump, and excellent coraline growth. The problem starts and ends with only my coral. No problems with hermits, snails, feather dusters, etc.
Could my extremely low nutrients really cause sudden tank wide STN? Which theoretically would be a "long term" stress issue that is no longer sustainable? I just have a hard time believing that every coral would be fine, to suddenly every coral declining on a nutrient issue alone. I should also note my Zoas and Rhodactis are doing absolutely fine and growing. Its ONLY my stony corals
