Coral Identification and care help needed.

[Fizzogg]

Hi everyone, I purchased a 'multi' pack of soft coral and aussie lord frags and have no idea what the soft corals are. Can you please help identify them and also tell me what I'm doing wrong as they don't seem to be 'growing'. I'm still very new at this saltwater thing so this is my first lot of coral. I thought I had done my research on care/placement/lighting etc. but nothing is working. I've had them since January. The Aussie lords (all 3 of them) seem dead but this is how they've always looked since I got them.

I've also noticed what I think is a tad bit of green hair algae, is this contributing to their demise and how do I treat that? (I have cheato in my sump)

There are also pink spots appearing on my rock, is that the good coralline algae or something else?

I hope the pictures are clear enough for you to see.

Sorry for so many questions and Thank you in advance for any info/advice.

Hi! I am in agreement that the acans look dead. Sorry about that. I also think the algae may be either GHA or worse possibly as it resembles bryopsis to me from the photo (would need a clearer photo to be sure).

The acans are dead. From the picture it looks like bryposis. or somethign along those lines. do you have a clearer photo

Most of the corals looks like it's well on it's way out. What kind of lights are you using and how long have you had this tank setup? Are you using rodi water?
