Instant Ocean salt check alk

[gregzz4]

Leanne, I heard about this too around x-mas 2011 and then experienced it myself
When I used my first bag bought boxing week, my alk was near 16
I mixed the second bag really well before using and it was still hi
I went through a bunch of bags curing rock and the alk dropped between bags 2 and 3, or so
Since then it's been closer to 9
The 6 bags I bought came in 2 boxes, so not much to explain the batches

I'll soon be opening my first bucket bought the same boxing week, so we'll see what happens
