Tank transfer didn't go well

Well thats why I asked here and at RC and both places got about 90% of people saying to reuse some of the sand after rinsing it. I honestly don't think its the sand or I would have had some kind of spike in ammonia and then nitrates. My nitrates are lower now than before the move. As for the water change, I have my doubts as well unless something bad was in the water. There is no way a 40% change should harm a tank if its done properly.

I am using the Deltec salt.

I don't know...like I said, I was so careful about how I did this and really made sure it was quick and parameters stayed the same. The only obvious change for some of the corals would be flow.
