This has always confused me, because it just doesnt really make sense. I was told first take out the water that needed to be changed, then add water conditioner (enough to equal the whole volume of the tank) and then add the tap water. But even with the conditioner in there prior to the tap water being added couldnt the tap just getting in there after get into one of your filter intakes and get in there and kill all your bacteria? I don't know it just seems like it to me? AM i doing changes right?
