I posted this in my Nano tank thread, but wanted to repost it here as well in case someone can help save my Coral's

What a sh@tty week.

Got my light fixture hung and that was all good and well. Decided to take my water down to calgary on monday to confirm that I was cycled, readings of zero across the board, so I grabbed a toadstool coral and a star polyp.

Took those home and all was well, the coral's seemed to adjust beautifully to life in the new tank.

Yesterday I had to go back to Calgary and stopped in at the store again, picked up a pair of tank bred clownfish (I figured with 15 gallons of capacity I would be ok) and a new powerhead. Acclimitize the fish just like I did the coral's (put them in a bucket and drip my tank water in gradually, it took about half an hour before I put them in the tank) Installed the powerhead, added the fish, all was well and happy. I checked on them before I went to bed and everyone seemed fine.

Came home from work today, clownfish are both dead, coral's look like they're on the way out. Other residents of the tank seem fine (2 hermit crabs 2 snails and a conch). I have no idea what could've caused this, as I didn't change anything at all between monday and today other then adding the new fish and powerhead. My parameter's are all fine, Salinity is good, Temperature is good Like I said as well, my inverts are all fine, but the fish are dead (I stuck them in the freezer in case I can return them), and my Coral's are on their way out.

I am really one unhappy camper right now, my coral's might still have a shot, does anyone have any idea what I should be looking for in order to give them a chance at recovery? Any help is appreciated
