I was considering a DIY kalkwasser drip with a one gallon container, some plastic tubing, and a standard valve from a hardware store. I was planning on dripping straight into the tank (55 gal. reef) since I do not have a sump. My questions are how much of a mixture should I use with a one gallon jug, and when it is empty if I should make another mixture or fill it up with R.O. water, shake, and drip again. Should I continue to use the fill and shake method a couple times before I make a new mixture or not?
