Your Complete Guide to Buying Pool Salt
Adding salt to your pool might sound strange, but it’s the magic behind saltwater chlorinators. These systems turn simple salt into the chlorine that keeps your pool clean and safe. Choosing the right salt makes a big difference in how well your system works and how long it lasts. This guide will help you pick the best pool salt for your needs.
Key Features to Look For
When you shop for pool salt, you need to focus on purity and form. These features directly affect your pool’s water quality and your chlorinator cell’s lifespan.
Purity Level
- High Purity is Best: Look for salt that is 99.6% pure or higher. High purity means fewer extra materials floating around in your pool water.
- Why Purity Matters: Impurities (like dirt or other minerals) can clog your salt cell, making it less effective. They can also cause cloudy water or scale buildup on your pool surfaces.
Grain Size and Form
- Solar Salt: This is the most common and usually the most affordable. It is evaporated using the sun. It might have slightly more impurities than other types.
- Evaporated Salt: This is made by boiling brine (salty water). It is generally very pure and dissolves quickly.
- Mined Salt: This comes directly from underground salt deposits. It usually needs more processing to reach high purity levels.
Important Materials: What’s Inside the Bag?
Pool salt is almost entirely sodium chloride (NaCl). However, what is *not* sodium chloride is just as important as what is in it.
The Good Stuff: You want nearly 100% Sodium Chloride (NaCl). This is what your salt chlorine generator needs to make chlorine. Simple is better here.
What to Avoid: Steer clear of “water softener” salts unless the bag specifically says it is safe for pools. Water softener salts often contain additives like anti-caking agents or corrosion inhibitors. These additives are designed for water softeners, not for swimming pools. They can cause cloudiness, foam, or damage your pool liner and equipment.
Factors That Improve or Reduce Quality
The quality of the salt you buy directly impacts your pool maintenance routine.
Factors Improving Quality (High-Quality Salt)
- Fast Dissolving: High-quality, fine-grained salt dissolves very quickly. This means you can test your water and adjust the salt level sooner after adding it.
- No Residue: Pure salt leaves no dusty residue at the bottom of the pool or inside the salt cell.
Factors Reducing Quality (Low-Quality Salt)
- Additives: As mentioned, extra chemicals lower the quality. They can create scale (hard white buildup) inside your salt cell.
- Slow Dissolving: Coarse or poorly processed salt takes a long time to dissolve. You might have to brush the bottom of the pool repeatedly to help it mix in.
User Experience and Use Cases
Using the right pool salt makes pool ownership easier. Saltwater pools feel softer on the skin and eyes compared to traditionally chlorinated pools.
Easy Maintenance
When you use high-purity evaporated salt, you spend less time worrying about cloudy water or cleaning scale off your salt cell. You simply add the salt once (when you first fill the pool or after heavy rain washes some out) and then maintain the level.
Safety and Comfort
The main benefit users love is the feel of the water. Saltwater systems produce a gentler type of chlorine, which means you avoid the harsh smell and drying effects often associated with chlorine tablets.
10 Frequently Asked Questions (FAQ) About Pool Salt
Q: Can I use regular table salt in my pool?
A: No. Table salt usually contains iodine and anti-caking agents that cause problems in your pool system. Only use salt specifically labeled for pools.
Q: How often do I need to add salt?
A: You usually only add salt once when you first fill the pool. You might need to top it up after heavy rain or splash-out, but it rarely needs regular additions.
Q: Does the salt get used up?
A: The salt itself does not get used up. The salt chlorine generator converts the salt (NaCl) into chlorine. The salt stays in the water unless it leaves via splash-out or draining.
Q: What is the ideal salt level for my pool?
A: Most manufacturers recommend a level between 2,700 and 3,500 parts per million (ppm). Always check your pool equipment manual for the exact number.
Q: Will the salt damage my vinyl liner or plaster?
A: High-purity salt will not damage standard pool surfaces. However, if the salt level gets too high, or if the salt contains impurities, it can cause staining or etching over time.
Q: How do I know when the salt level is too low?
A: Your salt chlorine generator will usually display a warning light or error message on its control panel when the salt level drops too low to produce chlorine effectively.
Q: What is the difference between pool salt and water softener salt?
A: Pool salt is pure sodium chloride. Water softener salt often has added chemicals that are harmful to pool chemistry and equipment.
Q: How long does it take for the salt to dissolve?
A: High-quality evaporated salt dissolves quickly, often within 24 hours if the pump runs continuously. Lower quality salt might take several days.
Q: Can I use salt meant for ice control on driveways?
A: Absolutely not. Road salt is extremely impure and contains chemicals that will severely damage your pool and filtration system.
Q: Is pool salt expensive?
A: Pool salt is generally affordable. While the initial cost of filling a pool can be high due to the large quantity needed, the ongoing cost is usually lower than buying traditional chlorine tablets.
