75 gallon empty , had africans but I had people over and apparentley someone ended upputting something in the water , all I know is they was fine and swimming and after the get together I noticed they was not acting right went over and they was all laying on their sides and breathing heavy checked the water and it was fine .... so I am not sure what happened but lost all 30 of them.\
i cannot believe this...that is awful sad.. sorry for your loss...
I do 20% water changes on everything 3 times per week and vacume the subrate at every water change also , clean the glass on the tanks every other day .
