Hopefully putting all that together someone can tell me possable causes why new Cleaner Shrimp, Coral Banded Shrimp, 2 Pencil Urchin, & a Feather Duster died this morning. There were put into the tank yesterday afternoon.

I also put 2 Pink Tip Haitian Anemones in the tank and they both have kinda sucked in them selfs. I never had this happen with my old setup. I Acclimation correctly as instructed. I also put 4 turbo snails in to but they seem to be ok.

does anybody know why this would happen? I'm thinking that the Alk might have caused this death so soon.

is your water RO/DI or tap? Sounds like some type of contaminant in your water, copper maybe?

Is your alk in Meg/l or DKH. I am assuming DKH where 12 wouldnt be deadly. Salliny should be 1.023-1.026. CA should be atleast 350. Shrimp need very slow acclimation time. And I usually acclimate them over a period of hours.

Did you test ammonia?

What is the daytime temp running on your tank?
