I'm Leaking!!!!!!

I would remove the sand for now. I have moved tanks and usually given the sand a good "wash" before using it again. You can strain as much out of it as possible first but moving a live sandbed can be tricky.

It is a good part of your biological filtration but you may have to start it over. If you have enough LR and a good skimmer, plus you are not too overstocked, then your fish should be fine in the new tank with the "washed" sand. You will just have to watch for spikes in ammonia and nitrite. But I have never had them in this kind of situation (moving tanks).
