From the sheer vastness of open water, to the potential for exploring seaside towns, even the challenge of jumping waves, ocean riding has much to … Answer: Low free chlorine (FC) levels in a saltwater pool is caused by 4 main issues; the first one is … Rust (hydrous oxide) is an example of this change that results when iron is exposed to water or damp air. Water enables fast oxidation, however salt water has a lot of dissociated ions which act as catalyst to cause corrosion. They eliminate the discomfort associated with normal chlorination systems and they are easy to maintain. Adjust Your Salt Levels. Thank you! If the screws are stainless steel, there is not longer a corrosion problem. Salt water accelerates corrosion. Saltwater corrodes metal five times faster than fresh water does and the salty, humid ocean air causes metal to corrode 10 times faster than air with normal humidity. Salt and other factors can contribute to this damage. A great way to check the overall chemistry in your salt water pool is to calculate the Langelier Saturation Index. (Note that this is about halfway between iron(III) hydroxide, Fe(OH) 3 or ½{Fe 2 O 3 •3H 2 O], and anhydrous Fe 2 O 3 ). A salt generator system will cut down on chemical costs of bromine or chlorine and eliminate having to add them regularly but all other water elements must still be tested and maintained on a regular basis just as they would need to be on any other system.Acidic water caused by unbalanced pH is another common cause for sped up corrosion. Therefore, rusting becomes more serious problem where salt water is present. Salt water pool systems offer conveniences for homeowners. The greater the concentration of sodium chloride, the more ions in solution and henceforth allowing more redox reactions to occur. ", "Took the time to explain everything so I could understand, always flexible, willing to go the extra mile. Galvanic Series In Flowing Seawater Unlike steel, aluminum resists corrosion by moisture and air when exposed to the elements, but salt spray and road salts can cause a condition caused oxidation, which discolors the aluminum surface. Corrosion can be prevented by wiping down the metals that are being exposed and taking care of maintaining the level of water salinity. 6 1 Basics of Corrosion Chemistry ions CrO2− 4 are the hard bases.BromideionsBr − and sulfurous ions SO2− 3 stand somewhere between the soft base and the hard base. When you are in the process of looking to purchase a salt generator system many people will try and tell you as part of their sales pitch that salt is not corrosive and will not cause any harm to your pool or equipment.
