I have a 75 gallon aquarium and was wondering how to add the kalk to the tank. I have to add about one gl of top off water each morning to the tank, so would I just add 1 teaspoon of kalk to the water and pour it in, or do I have to do something special with it? It kind of makes me nervous because I have never used this product befor, but everybody seems to think it is the best stuff to top off with. What exactly does this stuff do, that liquid calcium doesn't? Sorry for all the questions, but I am just not understanding this stuff.
