DIY Kalk Dripper

[Richer]

Generally, if you're going to use a simple dripper like the one Bev linked us to... its suggested that the mixture should be replaced one a week (or whenever you run out... which ever comes first). My container of kalk suggests using 1/8-2 tablespoons of the stuff per gallon of freshwater... depending on your tank. I think the only way to know is to actually try it, there are many variables to consider (ie. coral consumption, pH, alk, etc.).
