check the pH...... high chance pH crashed too low and as a result nitrifying bacteria can't replicate at optimal speed.... and as a result not able to cope with ammonia.

then again if the new fish all died off within 24 hrs, it's most probably due to the pH being too low and the new fish all got shocked/"burnt".
