Acans and Softies dying?

[bruindave]

Are these corals dying?

The acan in the middle of the picture (not the bottom one)

this toadstool which hasn't extended it's polyps in a few days

this devil's hand which has slowly shrunk and doesn't extend either.

this is a healthy acan i'm guessing.

i haven't really changed anything in the tank for awhile and haven't added much lately. i did add a small 2-3 eyed chalice like 3 weeks ago, but it's on the other side of my 28 gallon tank. the zoas around the chalice are doing ok.

any ideas?

My acan did this for a while... cant say for sure but looks like it wants more light some acans like more light i had to actually move my around because one didnt like light and the other did

Are you running carbon? Your leathers could be having a chemical warfare with the rest of your tank. Acans usually like to be on the sandbed with a moderate flow, lighting isn't as important to acans as good water parameters and a moderate flow.

What are your parameters? Full set please.

yes i am running carbon and a tiny bit of GFO.

sorry for the really delayed response, it's been busy. i ended up doing a 30% water change, plucked out all the algae around the acans and so far everything looks ok!

i appreciate the feedback from everyone. i'm going to do some more 30% changes once per week for awhile to try and see if i can get things back in order based on feedback. i'm going to try to test parameters with that too.

Thanks again!

Looks like you may be having some hair algae problems going on. You may want to increase the dosage of your GFO.
