loosing inverts.

I have a Biocube 29. Its been up and running for over a year and a half now. I have a clown, a yellow watchman goby, a sixline, a pistol shrimp, some random corals, and one crocea clam. since march i have lost 4 turbo snails, i believe one astrea snail is dieing, a peppermint shrimp, i believe my porcelin crab has died also. I am not sure why they are dieing. They seem to get stunned for a couple days, then just die. My snails will go limp, or pull into their shells for a day or two then are dead. My pepppermint shrimp was laying in my green stay polyps yesterday, which i thought was odd cause it usually never leaves the rocks, and today i found it dead. Porcelin crab was just laying on its side, wouldn't moves its legs but would move its antenae and back leg things?? around so i knew it was still living. Add Kent two part A&B every so often but that the only thing that has ever been added to the tank besides weekly 5 gallon water changes.

Most recent changes/additions to the tank were:
March: pistol shrimp, peppermint shrimp and watchman goby
April: 2 turbo snails to replace two that had died, and both new snails died shortly after.
Everything is acclimated to the tank for atleast 3hrs and everything is store bought.

Parameters with API test kit:
Ammonia: 0
Nitrite: 0
Nitrate: untraceble
Phosphate: untraceble
kH: 7-8
salinity:1.024, usually around 1.025, so i thought that was odd, but i doubt anything to be very alarmed about.
temp: 80-84 84 today cause it was rather hot here today, but normally temp is between 80-82.
I use Reef Crystals salt and Gallon bottled distilled H20

Could use any help in figuring this out. The only thing i could think of is that the pistol shrimp has moved all of my sand around, which lead to an annoying algae breakout which i am still trying to control. Would the pistol be stunning the inverts? or have released something into the water (from moving the sand around) that could not be takin out by water changes? I see no other stress in my fish, or clam.

Thanks for reading and comments!

The warm temps aren't good for the turbos. Sometimes bottled distilled can have copper in it which will build up in your tank and eventually start killing corals and inverts. RODI systems really aren't that expensive and can go a long way towards the health of a tank.
 
yea i am getting one on sat. so maybe if i do that, and do a larger water change that can help things...its getting too expensive to keep buying bottled...but i have also been using bottled for over a year now, so I wouldn't think it would just suddenly start affecting things...maybe ill get a copper test kit also and see if there are any traces
