Chlorine and salt are two alternative methods for pool water disinfection. However, each of them works in a different way, offering different advantages that are worth knowing before deciding between having a chlorine pool or a saltwater pool.
To get started, in the case of chlorine pools, disinfection is achieved by adding chemical products as needed. Whereas in saltwater pools, a salt chlorinator is installed, which converts the added salt into sodium hypochlorite. This substance serves as the disinfectant for the pool water, just like chlorine products do, but with the difference that it reverts back to salt each time it breaks down. The electrical consumption is very low, and it will not be necessary to change the pool water.
It is crucial to emphasize that seawater alone does not disinfect pool water, so a pool with salt but without a salt chlorinator cannot maintain itself in good condition. A salt chlorinator is necessary to carry out the disinfection process.
A common question that often arises is whether swimming in a saltwater pool is equivalent to swimming in the sea. The answer is that it's not the same since the salt level is much lower than in the sea. The salt concentration in salt-chlorinated pool water is 4 to 6 g/l, whereas seawater has a concentration between 34 and 38 g/l.
Choosing between a chlorine or saltwater pool is a very personal decision. It is advisable to analyse the pros and cons and determine which option best suits your needs.
If we look at the costs, installing a saltwater pool is similar to installing solar panels: the initial investment is high, but it pays off quickly, and you spend much less money over the years.
Still, chlorine is and will always be a suitable option, although the need for chemical products and a slightly more conscientious maintenance may make it more recommendable for pools that will not be frequently used by children.
Does this mean that chlorine cannot be used in family pools? Not at all, just that you will need to pay a bit more attention to how young children react to chlorinated water.
And remember that regardless of the option you choose, it is essential to ensure proper maintenance and ensure that water levels are in optimal condition. To determine the water levels, we recommend using "CTX 7-in-1" test strips if you opt for a chlorine pool or "CTX Salt" test strips if you choose a saltwater pool. Based on the results of the test strips, make any necessary adjustments to ensure proper pool maintenance.
