Assuming your limestone is all CaCO3 (if it isn't this will likely lead to
a slight underdose), to raise the hardness of 1000L =250 gallons of water 1
dH =18ppm requires 18g of limestone.  That is about 2/3rds of an ounce.  If
you have a postal scale, weigh out one ounce, that is enough for 375
gallons to increase 18 ppm.   Prorate as needed.
