change the range?



I bought a few Hach kits and the phosphate kit in particular doesn't read low 
enough to help me. The kit is 50 single dose sealed "pillows" of chem and a 
stepped comparator. If I use 1/2 the water amount will I be measuring 1/2 
steps in the range? In other words will a 1.0 become a 0.5?
