new tank cant keep fish alive

[harleynut155]

i set up my new tank its been running for about 2 months no ammonia or nitrites everything checks out ok but still cant keep fish alive its a 58gal with 80lbs of live rock and 3 inches of live sand can someone give me any answers

is it new? or new to you? was it ever used for a fresh water? if so they cold have put copper in it

 

[skyedolphan]

copper shouldnt effect fish

Best guess for me would be double check your salinity with someone else
back in the day I listened to a LFS which said salinity 1.006 couldnt figure out why I couldnt keep fish alive that was 8yrs ago umm duh had web tv at the time and decided to look around the web found RAG and ask the ? and learnt the answer 1.021-1,025 and acclimate slowly if you are not matching the stores salinity

Also check nitrates cause if they are high they could cause the deaths.

How are they dying? There could easilly be a parisite or disese living in the tank going from one sick fish and latching on to each new fish you add. We need more info about what happens to the fish, what kinds of fish we are talking about and their health and eating habits when they go into the tank.
