Atlantic Grazer snail question...

[Boca Kris]

I am brand new to this hobby. Started a 55 gal tank in mid march. Started with 5 Atlantic grazer snails, of which only 1 survived. I also started with 5 green chromis, of which only one survived. I also started with 6 blue legged hermit crabs and 1 emerald crab, all of which are doing great.

A few days ago, I added another 10lbs of live rock, 5 more green chromis, 2 mexican turbo snails, and 5 more Atlantic grazers, 2 of which were dead 2 days later.

Everything else in my tank seems to be normal. I was having an issue earlier with evaporation, but now I have a RO schedule down pat and everything is stabilized. All other inhabitants are doing great!

Any suggestions or ideas as to what might be doing them in?

How are you acclimating?
What are your water parameters?

Well, I bring them home from the store and set the container in the water for about 30 mins fot them temp to adjust. Then I put them in a container that floats on the surface and dump water into the sink, then fill it with tank water a little bit at a time over another 30 mins or so.

My water parameters are normal according to my test kit. I brought some of my water there, and they tested it also and said it was fine. It has only been tested for pH, nitrates, nitrites, ammonia, and SG.
