How much salt should be added to 5000 gallon pool raise it by 200ppm?

To calculate the amount of salt you need to add to your 5000-gallon pool to raise the salt level by 200ppm, you can use the following formula:

```

Amount of salt (in pounds) = (Desired salt level - Current salt level) * Pool volume (in gallons) / Salt conversion factor

```

Given:

- Desired salt level = 200 ppm (parts per million)

- Current salt level = 0 ppm (assuming the pool is initially filled with fresh water)

- Pool volume = 5000 gallons

- Salt conversion factor = 10 (This factor converts ppm to pounds per gallon)

```

Amount of salt (in pounds) = (200 ppm - 0 ppm) * 5000 gallons / 10

Amount of salt (in pounds) = 200 * 5000 / 10

Amount of salt (in pounds) = 100,000 / 10

Amount of salt (in pounds) = 10,000 pounds

```

Therefore, you will need to add 10,000 pounds of salt to your 5000-gallon pool to raise the salt level by 200ppm.
