Guide to Buy the Best Pool Salt
1. Pool Salt Type
Pool salt comes in different types, and each has its positive and negative attributes. If you have a saltwater system, it is crucial to know what each type is all about, as this makes it easy to decide what to use.
As the name suggests, this salt comes from the ground. Rock salt is the most common type of mined salt, and besides pools, it is often used on icy roads and as table salt. Mined salt is one of the purest as it will have a purity level of between 95% and 99%.
Solar salt comes from spreading seawater in the ground and allowing water to evaporate, leaving behind the salt.
The salt that remains behind often has tiny organisms from the sea, such as shrimp and contains many other minerals, meaning it has a low purity level. Further refining is often necessary to increase the purity levels and make it better for use in pools.
Mechanically Evaporated Salt
Mechanically evaporated salt comes from seawater like solar salt. However, instead of relying on the sun for evaporation, the water is heated using mechanical means.
The high heat used kills most microorganisms and bacteria, but it still does not solve the mineral issue, meaning the salt will still not be as pure as mined salt.
2. Purity Level
Regardless of the salt type you choose for your pool, it is crucial to make sure that it is pure enough, as this is what makes it effective at cleaning the pool and ensures fast dissolution.
Try to go for something with at least 99% purity to ensure there is no significant amount of other minerals. Having other minerals in the salt will make your water hard, leading to staining and scaling.
Some salt types like the AquaSalt Swimming Pool and Spa Salt has a 100% purity level. The high purity makes it an even better buy as it will never stain your pool, and you will not need to clean your chlorine generator often.
3. Granulation and Coloring
The salt granulation and coloring also matter a lot. For granulation, pool salts that have food-grade granules that are more even are the best.
Even granulation ensures the salt dissolves fast without ever pooling at the bottom of the pool, which is what leads to staining.
When it comes to the color, look for something with a pure white shade that looks more like your regular table salt. A pure white color indicates high salt purity.
4. Additives and Other Ingredients
Some pool salts will include additives to prevent clumping or staining. While they might sound more beneficial for your pool, they are not. Instead, it is always best to go for a salt that does not include additives or other ingredients besides sodium chloride.
Pure salt with no additives like Morton Salt 3460 Pool Salt works better with your chlorine salt generator and will ensure you do not have difficulties balancing your pool’s chemistry.
You need the best pool salt to keep your saltwater pool sanitized. Luckily there are more than enough salt brands for pools out there, and our review above narrows down the choices for you.
That said, the AquaSalt Swimming Pool and Spa Salt is our top recommendation as it has all the good features from 100% purity levels to fast dissolution and an additive-free formula.
However, if you are on a tight budget and prefer something that will give you the best value for money, the Clorox 81040CLX Pool Salt is our recommendation.
