Hey! What size tank and what stock? Also we need to know your water parameters. It sounds like it introduced a disease into the tank. What symptoms did they show before they died?

the tank size is 4ft bt 2ft by 2ft its quite a large tank .two sharks started shaking for a few hours and then died the little loach died the next day but the angels and mollys are fine
