Alk 2.9 (This might not be acurate, I use redsea kit and they don't give you an exact #. They give you a color chart and mine is on the high side of normal, green, but nit quite blue. So I chose the highest # on the normal chart)
Calcium is 400.
You can use it occationally if you like. With calcium at 400 then your alk (if you are expressing it in L/meq should be more like 2.0, but with an alk of 2.9 then your calcium should be more like 420,.. So in any event your not far off the mark.
