Thanks Carmie. My method is similar, except I measure exactly 750 grams of salt using a digital scale, which puts me spot on when I double check the
SG. My pump of choice is a Maxijet 900 with a Sure Flow propeller kit, since I had one that I wasn't using. Does well to churn up the water.
However, my last batch I did in a 5g food-safe bucket (instead of my Brute), and I churned and heated the RODI water (lid off) for 12 hours before adding the salt. The results were the same for every parameter except
Alk. Last time I double-tested the Coral Pro salt at 7 dKH. This time it was 9 dKH, just as Bobby has indicated. Unfortunately, the Mg in this Coral Pro bucket is still low, as it tests virtually the same (870
ppm - Salifert) it did last time.
Is it odd that the
Ca can be so high when the Mg is so low?
