1. What is the Salt Calculator?

The Salt Calculator determines how much salt you need to add to your swimming pool to reach the ideal salt concentration for saltwater chlorine generators. Maintaining proper salt levels ensures efficient chlorine production and protects your equipment.

2. How Does the Calculator Work?

The calculator uses the following formula:

\[ \text{Salt\_dose} = \frac{V \times (\text{Salt\_target} - \text{Salt\_current})}{10,000} \]

Where:

Explanation: The formula calculates how many pounds of salt are needed to raise the salt concentration from the current level to the target level in your specific pool volume.

3. Importance of Proper Salt Levels

Details: Most saltwater chlorine generators require salt levels between 2,700-3,400 ppm for optimal operation. Too little salt reduces chlorine production, while too much can damage equipment and cause corrosion.

5. Frequently Asked Questions (FAQ)

Q1: What type of salt should I use?
A: Use only pure sodium chloride (NaCl) without additives - pool salt, water softener salt, or food-grade salt. Avoid iodized or anti-caking salts.

Q2: How often should I test salt levels?
A: Test weekly during swim season and after heavy rain or backwashing that might dilute pool water.

Q3: How long should I wait after adding salt?
A: Run your pump for 24 hours to fully dissolve and circulate the salt before retesting.

Q4: Can I add too much salt?
A: Yes, excessive salt (>4,000 ppm) can damage equipment and cause corrosion. If levels are too high, partially drain and refill the pool.

Q5: Does salt evaporate from the pool?
A: No, salt remains when water evaporates. Salt levels only decrease from splash-out, backwashing, or dilution from rain/refill.
