Sorry to hear about your lost. I recently did a move and lost 75% of my sps colonies, that's about 25 pieces, some were over 12" in diameter.
I cried for a few hours but I had prepared myself for such a lost, so it was understandable. I planned the move as best I can, but in the end time was the factor and the stress of the long move (8 hours in transit) caused many casualties. Ammonia build up caused by stressed corals and released toxin/slime was the culprit.
How much sps did you have? I can almost say that your losts was due to reasons similar to mine. Hope it recovers fast for you. My best advise is skim skim skim and you want as much algae to grow as possible to help polish your water.
