I just had to do a tank swap yesterday due to bad seam on my old tank. All new sand, and 100% new water. It went well. Fish all look great but I brought water to lfs to test. Nitrates are 52 why would this be after 100% water change. Phosphates are very high also.

Probably need more information to diagnose.
- Where is the fresh SW coming from
- ^ anything besides fish that was moved (liverock like mentioned above)
- State of the new tank, did it come straight from store, old tank that got cleaned etc.
- Are you using a sump and what is its state etc.

No I was standing with them when they tested.
Doesn't seem like anything on the rock died. But I suppose that could be something. Rocks came out of old tank straight into buckets of water, sat for about an hour then right in to the new.

A couple ideas:
1. You say rinsed the sand in tap water... There could be nitrate/phosphate from that trapped in the sand.
2. The rocks could have a lot of muck embedded that is releasing nutrients into your new water.
