Ode, I'm using the Puppy & it is working  great...Questions--  
!. Is it possible to make good EIS in 2-3 hours..I  seed my distilled 
water, in a quart canning jar, with about 2 TBs from my last  brew & warm the 
DW 
by putting the jug in hot water in the  sink...
2. Is it possible to tell if you have a brew with good  ppm. by using the 
laser. I shine the light ( red laser ) threw the brew &  get a good strong 
line...
  The fact that it is brewing in only 2-3  hrs. Has me wondering if it is 
strong  enough..Thanks for any help you can give...  Lois
