I got the kit, started the new chlorine test, and couldn't get the water to turn pink - I check with the old HTH kit, and got 0 total chlorine and a pH of 6.8. (strangely enough, the pool was noticably clearer though)

So I added 4 boxes of borax, 9 gals of chlorine (per The Pool Calculator) and waited 5 hours.
Then I got the following k2006c results:

FC: 3 ppm
CC: 1.5 ppm
CYA: 110 ppm (slightly more than 100?)
pH: 7.2
Alk: 80 ppm
Cal: 100 ppm (I do have a plaster pool)

So more chlorine? 8 gals by the calculator (3 -> 20 ppm)?
More borax too?
