All sands are prep rinsed in unlimited tap water, final rinse in ro to evacuate the rinse tap, that new sand will be cloudless
for your tank swap catch and hold the fish, keep them covered so they won’t jump out, and drain off 75% of your current tank water to just put back in on top of cleaned sand. This means you aren’t making 100% new water for the job you’re making about 25%
if you drain the current water all the way down for re use the last 25% will be full opaque clouding as the water level gets close to the sandbed so toss that water
nobody needs bacteria in a sandbed. theyre expendable it’s why bare bottom reefs or frag tanks work just fine without sand. That’s why fifty pages of tap rinsing produced great results not bad ones, we don’t need sandbed bacteria in reefing so blast rinse them away along with the silt.
