tank confusion

[jenbear]

:help:

i have a 29 gallon tank, i am a new salt water enthusiast. i started out my tank with damsels, and crushed shells. my water levels all checked out to be good. after a month i added two more damsels, they were more agressive with in a week they had killed all the other damsels, and then deid themselves. ever since then i have tryed other fish and shrimp, and within a day they are all dead. each time i have the water tested, and it tests out great. but each time i add new fish they die. i just added live rock and a clown and shrimp, per the store, and once again the water tests perfect but a day later the fish all are dead. please help.......why is this happening???????????????????????????

what water tests are you doing?
O2?
if damselfish are not making it then nothing will.
i would clean out anything in my filters (change all media).
do a 100% water change,
get more LR and let it cycle for 30 days.
check your system.
do you have good skimmer, lighting, heat, and water flow???
sometimes one never knows what happend.
good luck

Hello, and welcome to Saltwaterfish.com. Sorry to hear about your troubles.
What exactly are your water readings? And, when did you set up the tank? Details on the tank and setup would be helpful.
And, what are the fish dying from? Notice anything wrong with them before they die? Symptoms?
