I don't know about Calcium and Mg but we all know that the Alk testing reagents can be made for a fraction of the cost. If we assume all of them on the kit are selling for an equal amount then the $11 for 500ml of Alk reagent is high when compared to .1m Acid which is about $38 for 4 liters retail. God knows what it cost when you buy it in 55 gallon drums wholesale. Only other factor is the pH color changing chemical like Bromothymol blue which i bet is also very cheap in bulk.I don't know. Is it nuts?
