FORMULA HMC = A x ( B1 ÷ B2 ) x (C1 ÷ C2) |
|
HMC |
= How much chemical |
|
A |
= Amount of chemical from the CPO Durham handout or book |
|
B1 |
= the size of your pool |
|
B2 |
= 40,000 L. |
|
C1 |
= Your desired change |
|
C2 |
= The amount of change in ppm in 40,000 L. |
EXAMPLE
Your pool is 585,900 L.
Raise your Calcium Hardness level 200 mg/L using Calcium Chloride (100%)
HMC = A x ( B1 ÷ B2 ) x (C1 ÷ C2)
HMC = 402 grams x ( 585,900 ÷ 40,000 ) x (200 ÷ 10)
HMC = 402 grams. x 14.6 x 20
HMC = 117,384 grams ÷ 1000
HMC = 117.384 kg or 117.4 kg.
