Update... got home from work yesterday and things weren't looking a whole lot better... The bloom was not as strong but the water was still a bit cloudy. I ended up pulling all the SPS out of the tank that I could and took them to a friends tank. Most of the softies look alright but I did lose a couple SPS.

Not entirely sure what happened yet as all the water tests check out ok. I think that dying algae may have released some sort of toxin into the water and that coupled with the stress from the bloom caused the coral to bleach. I also lost my pair of orange-lined cardinalfish which was sad, but my possum wrasse survived (my only good news).

Did another 25gal water change in the evening and this morning the water is all cleared up and I things look back to normal. There are still a couple SPS in there that seem to be holding on so we will see if they recover. Thanks to everyone for the quick responses. I knew what to do but sometimes in a panic you second guess yourself! Thanks again!
