Whats happening to my corals?

[Pegasus]

As far as the clam goes, my money is on the angels.

As far as the corals go, well what can I say. My experience with Acros is that they are very sensitive animals and may not liked how they where transfered.

If I read your post right, your adding another 440 w MH to a 77 gal tank? Won't that make more than 11 w per gallon? I don't know how you are going to do this but hopefully gradually? Some say that this may be too much light.

Hope this helps
