hey, I'm trying to find a more precise way to dose calcium chloride (which ive been using for years) anyway I'm trying to do the math, i just need a double check here:
my tank ~265-270 litre
molar mass calcium 40.08 g/mol
molar mass Chlorine 35.45 g/mol (2 of them in CaCl2) = 70.9
proportio of calcium is 0.3676
1 mol CaCl2 = 110.98 g = 110980 mg
dissolve in 1 litre of water = 110980 * 0.3676 = 40796.248
110.98 grams raises 1 litre of water to 40796.248 mg/litre
sooo 1 gram of cacl2 should raise water by 40796.248/110.98= 367.6 mg for 1 litre
so add 1 gram to 1 litre and it will raise the waters Ca by 367.6 mg.
sooo 265 litre... 1 gram raises it by ... 367.6/265 = 1.387
so if i want to raise it by 20 mg/L - 20/1.387 = 14.42g
Correct? just helps use less calcium tests hehehe thanks!
