A pool that is 18x48 and 4 feet deep is about 26,000 gallons and would take 750 lbs. of salt to get the salt level up to 3400 ppm...
Water capacity is 6,423 gallons (90%) and it is ready for water in 60 minutes.
To reach the initial salt level recommended by the salt system manufacturer (usually 2400-3200 ppm), you will need to add about 200 lbs of pure pool grade salt (NaCl), per 10,000 gallons of water. Salt stays in the water, you only need annual boosters, to replace salt lost to backwashing or splashout.
The ideal salt level is between 2700-3400 ppm (parts per million) with 3200 ppm being optimal. Before adding salt to your pool, test the water to check your salt level. If the level is low, determine the number of gallons in the pool and add salt according to the chart below.
3400 is the recomended high limit, but the readings on the panel are notoriously inaccurate. Generally it's better to have the level on the high side than low, so 3800 should be fine.
Bottom Line. A little bit of extra salt in your pool doesn't generally result in any concerning issues. However, putting in excessive amounts of salt, resulting in salt levels 5000 ppm or more, can lead to corrosion of your metal pool equipment. Not to mention, having too much salt will also make the pool saltier.
For example, for an 18 ft. pool 4 ft. high you would multiply 18 x 18 = 324. Then 324 x 4 = 1,296.

Therefore, if you have a 20,000 gallon pool and want to determine how much salt you'll need to buy, you would use the formula “30/1,000 x 20,000”, which equals 600. Meaning, the pool would require approximately 600 lb of salt.
Just like a chlorine-based pool, saltwater pools turn cloudy when chemicals are not balanced. You need to ensure that all chemicals are balanced all the time to avoid cloudy water and growth of algae. The major causes of cloudiness are chlorine, pH, Salinity, total alkalinity, cyanuric acid, and calcium hardness.
It's recommended to wait at least 20 minutes to swim after adding salt to your pool. If you're adding calcium chloride to your pool water, it's recommended to wait two to four hours before swimming again.
Pros of Saltwater Pools
There's less chlorine and less of the heavy chemical scent and content. They're gentler on the skin, with less irritation to the eyes, hair and swimsuits. The water has a softer, silkier feel to it compared to chlorine water. They have lower maintenance costs than chlorine pools.
The ideal salt level in the pool water is between 2500-3500 ppm (parts per million) with 3000 ppm being optimal. A too low salt level will reduce the efficiency of the Saltwater System and result in low chlorine production.
Length times width gives the surface area of the pool. Multiplying that by the depth gives the volume in cubic meters. If you'd like to find the pool volume in gallons, multiply your results by 7.5, as there are 7.5 gallons for each cubic foot.
The answer is 56.57 .
Light Green or Teal Pool Water:
In this case, you should double shock your swimming pool water. To double shock, you will need to add 2 pounds for every 10,000 gallons of water. For instance, if you pool is 20,000 gallons, you will add 4 pounds of shock.
It takes nine hours to fill a 5,000-gallon pool at 540 gallons per hour.
