OK
I received my new box of 200g Fritz yesterday. I mixed up a fresh batch just to test
Mixed about 6 gallons adding salt slowly over about 15 minutes.
Temp 76 degrees .35 Salinity.
I let it aerate for another 20 minutes.
All test are Salifert
Alk - 9.5-10 (from first turning orange till no further change)
Cal - off the chart >500 ( never started to change )
Mag - off the chart >1500(never started to change)
Ran the test again an hour later after aerating (no change)
I'm not all that concerned because my system is about 250 gallons total water volume and I have to dose anyway. But this does explain why I never have to dose Mag and I dose less Cal then I thought I would.
