Excellent question! So I will tell you what it is has to do with disease.
Fish health is the most important factor in preventing fish disease, thus a tank that is in a less than ideal condition, can and will effect fish health causing disease.
I would wait until the dust settles with the tank. I would consider suspended sand particles in the water column to be less than ideal, as fish breath water. Sorta like us breathing in sand in a dust storm.
This is exactly why we MUST age our salt water. Salt needs to be throughly mixed and dissolved in the water before we add it to a tank that has living creatures. Undesolved salt even being more detrimental than sand.
