cleaning crew death

Ya, they (depending on type of animal) can be really sensitive to salinity changes, etc. It's recommended that you drip tank water into holding water to equalize parameters. Although, I wouldn't expect everything to die. I have just dumped 50 snails into my tank (long bus ride caused water to foul) and out of 50, I lost a couple.

To properly acclimate them you need to drip water into there bag or bucket for at least an hour with a drip rate of about 1 drop every 2 seconds or so. I just grabbed some airline tubing and a valve to build my acclamator. If I was doing it again I would find a U shaped ridgid peice to hang off the tank.
