Remove salt stains from pool

In recent years, there has been a significant increase in cheap and low quality salts sold in Australia. These low quality salts are not graded to the same standards normally seen in Australia. Some large hardware retailers buy enormous volumes of lower grade salt and sell it at very low prices. As a consequence, issues with heavily contaminated salts and salt staining in swimming pools has increased.

Salt stains can appear in several forms and colours. For example, cheap pool salt with small metal fragments can cause very small rust spots to appear. Furthermore,prolonged use of salt with a light brown (minerals) appearance can lead to general discolouration on the pool surface over time. Remember, it is not the salt that stains your pool but rather the minerals and metals found in low quality salt. To read more about this click here.

What causes salt staining in pools

1) Poor quality or contaminated salts.

Some inexpensive salts have large, light brown crystals (grains) which take longer to dissolve which can increase the chances of staining. Always make sure that your pool salt is thoroughly dissolved and not left undissolved on the floor of the pool. The minerals in low quality salts can leave a light brown haze on the surface of your pool. You can see examples of what that may look like here.

​2) Poor methods used when adding salt.

Some pool owners will pour the entire bag of salt in at the shallow end of the pool hoping that water movement will simply dissolve and distribute the salt over time. Although most pool owners are smarter than this, concentrated salt stains are still a very common type of staining. Be sure to disperse the salt around the entire pool and then brush it until it is completely dissolved. Good quality, fine salt should dissolve very quickly when added to the pool water. Therefore, if you find that you are spending a long time brushing to dissolve your pool salt, you may want to try a different brand.

3) Contaminated or mineral rich salt grains.

Salt can sometimes have individual discoloured crystals in the bag. Even the very best quality salt will have the occasional contaminate from time to time. If you experience this frequently, you may want to consider changing your brand or supplier of salt. Remember that cheap salt is cheap for a reason.

4) Adding salt when the water is out of balance.

When the pH of water is high, water loses its capacity to hold microscopic minerals and metals in suspension. This means that the brown minerals and metals often found in pool salt will plate out (or precipitate) to the pool floor and walls and leave a dark stain. Therefore, salt staining will most commonly present as a dirty brown colour or dark grey depending on the colour of the pool surface. Salt will rarely leave a white stain in your pool and will almost always be brown or grey coloured. So always balance the pool water BEFORE adding salt.   If you have white stains or lumps in your pool click here as you most likely have calcium.
