Hello

My tank is a 70gal , my water parameters are
ph - ~8.3
nitrate - 0
nitrate - 0
ammonia - 0
calcium - too high to read
carbonate (KH) - >200
Hydrometer - between 1.022 & 1.023 (refractometer on the way)
Tank is 3 months old with only 2 small Clowns and a bicolor blenny, these have been in the tank doing excellent for a month now.
35lb of liverock so far and a 4in florida crushed coral sandbed.

Ok now I get to the question, every shrimp I have tried , peppermint , cleaner or fireblood dies. The two starfish I have tried died . Most snails die , although they do live longer than the shrimp. I am in Africa right now and my wife sent me these parameters and I though i would get some advice before I get home. I recently got an RO/DI unit and when I get home I am planning on changing out all my water over a couple weeks ( Would this me OK). I have not added any Med's or anything to the tank.

I was into freshwater before and sold it all off to start this saltwater tank. I am not planing on adding anything in the near future, until I get all my LiveRock in and cured. Just wondering if anyone has any idea why I am having trouble with inverts.

Thanks
Frank
