HEEEEELP

[2 fish]

I have a 140lt tank, 2200lph back pack filtration with skimmer, 2 x 802 powerheads, 2 X 30w flouros 12 kg LR,25kg SG,1 green polyp,1 christmas tree, 1 anenome,1 pecula clown,1 fiji damsel( who is out real soon)1 blue damsel,1 talbot damsel.
temp26o,SG1.022,PH8.1,ammo0,trite0,trate0,phos0.25,free iron0,calcium440,KH 60( a bit low)
I came home today to find the soft corals on my LR is starting to die,Why????
I'm thinking maybe the fiji damsel is nipping at it as it has white marks on some of it and he tries to nip the christmas tree worms as well.
All other tank inhabitants are fine, but the soft corals are looking very sad, I am starting to get really worried, and any feedback I can get will be greatly appreciated.

Have you actually seen the Damsel nipping at the corals? Do you have any crabs or invertibrates? I had an Emerald Crab once that loved polys. I would say it is a possiblility that the fish are nipping at them as well.
Sorry that I can't be of much help.

Since thats what about a 35gl tank you are going to begin to have problems with the lighting - you really need to upgrade it. If not already - your anemone will have problems and most likely die.
