Chemical Dosage Chart – Pool Water
(Per 10,000 gallons of pool water)|
Which chemical are you adding? Write the "AMT" from the chart below in BOX A |
What is the "VOLUME FACTOR"? Write the number from the Volume factor chart in BOX B |
How much are you increasing or decreasing the level (in ppm)? Write the amount in BOX C |
Box C Example : Your TA is 50 & you want to raise it to 120. The increas = 70 ppm Note: Box C does not apply to pH adjustments |
|||||||||||||
|
IMPORTANT : To reach Chlorine Breakpoint, TAC – FAC = CAC. Multiply the CAC level times 10 and insert the amt in Box C. The CAC level should not exceed 0.2 ppm. |

For Volumes > 10,000 or for odd volumes not listed: divide the volume by 10,000 to calculate the factor. Example: The Volume Factor for 27,000 is 2.7 (27,000/10,000) |
