More on CaCl2.
CaCl2 comes in three varieties; anhydrous, di hydrate and 6-hydrate. It makes a difference. The tech grade CaCl2 (deicer) that I have appears to be the di-hydrate.
I used my tech-grade material to work out CaCl2 dosing empirically and found that it gave 1 degree of hardness/teaspoon/50 gallons of water. That is 7 ppm Ca per teaspoon per 50 gallons of water, and it is consistent with my theoretical calculations. The fertilator says that dose should produce 0.85 ppm calcium.
Someone using the fertilator to dose CaCl2 should get a lot more calcium then they bargained for.
