Help cc starfish dying?

[87ford]

I have a cc star for about maybe a month and I noticed he is missing a chip and
Has small pin holes he is moving and sticking to things I just gave him some krill incase he hasn't eaten anything? Is he decomposing
My tank is in great shape it's a 36 gallon now 2 power heads a filter a protien skimmer heater of course top of system and a aquatic life 4 bulb ho t5 the water parameters 8.0 ph 0 amonia 0 nitite 5 nitrate just did a 15% water change and did a dose of iodine I checked for copper I have none but I noticed the trace elements dose contains 3mg/l of copper I only used that a long while ago when I first had him in for a week is that dose even safe cause I wasn't thinking of the star I just knew the anemones need trace elements and used it I use or water is there something I'm doing wrong I just trying to make sure he doesn't perish

The pic to the right you can see a chip missing it's hard to see the small pin holes every where but he does move he is t now cause I places him over food so he is eating

Thanks
Tom

IME, all my CC stars that began to turn white or lose chips means it's a goner.

Ugh he doesn't even act sick he is at top of tank right now so he is moving around man this hobby is so so so temperamental

I would say the copper isnt adding anything good for you, from what I know adding copper to any inverts/corals tank is destructive and will leave you with a fowlr.

Ok thanks I stopped adding it cause I saw copper and I guess I'll toss it can I use it in a freshwater tank do you know ?
