Hey guys so one by one I have been having my Duncan’s die and loose all the flesh on the skeleton. It bleached out and then works it’s way up to the top where it’s far too gone by then. I did two big water changes in the past week and today my Duncan has lost so many heads. The only thing I have to add is would my fuge take too much nutrients? How do I know when to throw out the cheato and trim it. I literally have pounds.

The aptasia around the Duncan isn't helping him grow much, the flower pot coral I cannot give you good advice on since I have no experience with myself, and I don't know what the last coral is but there seems to be another nem near it? Are your nitrates near 0? That's when nutrients are too low mine usually sit at 0-2ppm and my duncans are pretty happy

what are your parameters. ?
I would set up a quick quarantine tank, using half new, half tank water............place some chaeto and live rock, and good lights.
did you feed the duncans before ?
They do need nutrients beyond the photosynthetic carbs that the lights give them. Many times the nutrients are in the water, and they absorb them.
Sometimes you have to dose.
Mine, I do spot or target feeding them with brine shrimp, mysis, which have been soaked in coral vitamins , plus some self made frozen food.
All mine are opened up..........
And this is with very little water change.
I doubt it is the chaeto ................even if they dissolve and release nutrients, duncans should do fine.
COuld it be some stresses that caused the palyzoas that you have, release their toxins ? DId you nick or scrape one of the green palyzoas, so they died and released toxins ?

The reef is really a multiple factorial complex system that has many organisms. Each with its own changing needs in food , water parameters , space , oxygen , light. , water flow , Etc
We only measure alkalinity, calcium. , salinity , magnesium , pH. , Nitrate. Phosphate. , and maybe ammonia and nitrite
We leave out the other 20 to 50 trace elements , other perhaps unknown but crucial parameters that may cause an imbalance or livestock death
But overall. As long as we get close to the big parameters. Then we are good to go and able to keep many species alive
Still there are challenges ahead
No one measures the laundry list of crucial amino acids , elements , organic compounds , etc. That each fish and each coral and each snail or crab or clam needs. No one knows. We can make educated guesses and set hypothesis. But the myriad of complex interactions is just too complex
For example : us humans have a pain pathway that involves at least 9 steps “a cascade “ . Each step requires a factor and other things to make the next step happen.
A simple lower animal may not need as many steps or compounds to have said effect. But multiply this by so many complex animals and interactions. Then we get an inkling that we are just understanding maybe 10 or 20 % of what goes on inside corals and fish and their inter species and intra species interactions.

My duncans are fed every other day. Aptasua I agree are irritating them im sure and flower pots do have feeder tubes and could be stinging them.
Chaeto looks Very healthy. Bad chaeto will be slimy/stringy and smell.
Lighting change could have had an affect but duncans arent picky when it comes to light. They do best in moderate water flow
