Saltwater Chlorine Generator (SWG)<\/a> uses electricity to convert salt to chlorine.<\/strong> As the chlorine gets used up, it turns back to salt, ready to be reused. With an SWG, you are yet using chlorine; the SWG simply helps to add the chlorine for you.<\/p>\n The salt levels vary between models. They are approximately 3,000 ppm. These levels are much lower than ocean water, which is around 35,000 ppm. Folks will be just able to taste the salt. Most individuals will only be barely able to taste the salt. In addition to letting the SWG work, adding salt also develops the subjective quality of the water.<\/p>\n SWGs are intended to produce modest quantities of chlorine continuously.<\/strong> This is ideal for daily use and enables you to use a bit lower FC levels than you require when adding chlorine manually.<\/p>\n Adding salt into the pool does a little bit to increase the chance of corrosion. Rarely any SWG owners encounter difficulty with corrosion. There has been debate in the industry regarding the use of SWGs because dangers for some of the substances are not well understood.<\/p>\n The two most frequent situations where harm has occurred are in indoor pools, where the FC level was allowed to get far too high. If you have one of the milder types of natural stone (limestone, sandstone, etc.) over the waterline, and the stone gets splashed frequently, such as in a waterfall.<\/strong> In both of these scenarios, problems are rare.<\/p>\n It’s essential to be aware that salt chlorinators do not make a chlorine-free pool.<\/strong> They use dissolved salt to produce chlorine to clean the pool.<\/p>\n Saltwater chlorinator<\/a> makes hypochlorous acid (HClO) using sodium chloride (NaCl) or table salt and electrolysis.<\/strong> The saltwater moves through an electric current producing chlorine gas (Cl2), but you are also forming sodium hydroxide (NaOH) and hydrogen gas (h2).<\/p>\n With electrolysis, dissolved salt is converted to sodium hypochlorite and hypochlorous acid (HClO), the sanitizing agents, used to remove the water of dirt and germs.<\/strong><\/p>\n <\/a><\/p>\n Now that we know how the basic chemical process works let us have a more in-depth look at the fundamental parts of a salt generator.<\/p>\n The cell is the section of the salt generator that turns salt into chlorine. Water crosses through the cell and above with iridium or ruthenium coated solid plates. These naturally occurring metals are charged from the control board turn the salt to chlorine through electrolysis.<\/p>\n The control center of the system, its primary purpose is to give electricity to the salt chlorine generator for the transformation process. Additionally, it lets you control the quantity of power sent to the mobile, thus allowing you to increase or reduce the amount of chlorine in the pool.<\/p>\n It is essential best to keep your pool’s chemical balance<\/a> used with an SWG.<\/p>\n Most SWGs give a percentage setting that regulates how much chlorine they produce. The percent of the time chlorine is pumped, is controlled by the setting.<\/p>\n To generate more chlorine, the percentage decreases to create less chlorine. Since the setting is a proportion of the pump run time, you’ll have to readjust the percent if you change the pump run time. In rare circumstances, you might have to raise the pump run time to have the ability to create enough chlorine.<\/p>\n To discover the right SWG percentage setting:<\/strong><\/p>\n Chlorine need will vary with the seasons and depend on how many people are swimming in the pool.<\/p>\n You must test your FC level weekly to see if you will need to adjust the percentage setting. It could be possible to test a bit less often as you gain familiarity with your pool.<\/strong><\/p>\n Storms, pool parties, and hot weather may need to manually add some chlorine to strengthen the chlorine produced by the SWG.<\/p>\n If the FC Level falls even though the SWG appears to be functioning, there are a few things to check. Confirm the CYA level. The SWG might be unable to keep up if your CYA level is becoming too low. You might have algae. A pool with an SWG may have algae even when the water is clear. Third, there may be some issues with the SWG, but this is much less likely than the first two possibilities.<\/p>\n SWGs aren’t Good at SLAMing (or shocking<\/a>) the pool since SLAMing is dependent upon the FC level going up fast, and an SWG only adds chlorine gradually. If you’re slamming the pool, you need to manually add chlorine.<\/strong><\/p>\n An SWG can help keep the FC level during SLAMing, but the first addition of chlorine to shock level must be done manually.<\/p>\n
