Amount Of Salt For A Pool

by Heather

We have a 16 ft wide by 4 ft deep pool. We converted from chemical to a salt water filtration system.

My question is, how much salt do we put in once it is filled and ready?

We are using the Morton pool salt 40 lb bags.

Thanks for the question Heather

For an average 20,000 gallon pool you will need 7-10 50lb. bags to bring your saline level to the correct reading of 3000-4000. It's important to know the range for your salt cell. Some are pretty strict, between 3000 - 3500ppm, while other are more forgiving, between 2500 - 4000ppm.

According to my calculations, you have a 6,000 gallon pool. Start with 2 - 3 bags, allow for one full turnover of the water. This is normally about 8 - 10 hours, then test the salinity. Keep filtering.

After you add the salt, be sure to sweep the bottom very well. If salt is allowed to sit on the floor, it might stain.
