Swimming Pool Salt Calculator

  1. I have read a lot of articles on this site on the pros & cons of salt chlorination vs traditional chlorination.
    I was wondering if it’s possible to have a both salt & traditional chlorination system for a swimming pool.
    And then based on necessity switch between the 2 systems if cost is not an issue.

    1. In theory, yes. But usually, you would switch to salt and only use shock to supplement the salt cell in cases of high demand. If you are going to take the money to switch to salt, it would seem a waste of money to keep adding chlorine tablets or liquid as well.

      1. purchased a small above swimming pool (10×30”) I put 1oz Clorox(shock extra blue) the chlorine is perfect but the ph is low, I am not an expert in pools since my husband was the one in charge of everything but since he passed the way, nothing is the same, my granddaughter is staying with me in the weekends so I had to got at list a small swimming pool but do not really know how to keep clean. Can you give an idea in how to to keep clean? This pool is only 1475 gallons.
        I would prefer to do not use chlorine just salt but I don’t know how much

  2. I purchased a Summer Waves above ground po model number sfx1500. it said it has like a little over 5,000 gallons of water how many bags of salt do I add to it 4 saltwater pop

  3. First time Salt water change over with a sand filter pump 8600 gals/18″ x 48″/Round, Coleman Swim Vista Series II pool just thinking better all the way around to change chlorine to salt. Filters to Sand instead but I’d be starting from new I have zero idea how much salt but I’m researching with help from your Salt Calculator this type salt and sand is new pool chemistry for a 20yr above ground normal chlorinated po person Don’t know if it’s easier or complicated
    Terrified as 1st Timer…Newbie on Sand & Dalt

    1. I changed to a salt water pool 2 years ago, after years of having a chlorinated pool. That I would not go back to.
      My salt water pool has it beat all the away around. Way less chemicals to mess with. Hardly any of the problems with keeping it ready to swim. The burning eyes, and green hair and bathing suits with elastic in them don`t wear out as fast are GONE. Now its softer skin.
      Good luck,
      Never going back!

  4. Getting a 15 ft round pool by 48 inches. Probably fill to 44 inches. Having a hard time figuring out salt requirements as your calculator and tables start with much bigger pools, more gallons of water. Any help? Also any recommendations on converters would be appreciated. Plan on keeping pool up for the season only. First time real pool buyers. Excited and nervous.

    Thanks.

    1. Mine is a 16’x42″ and I normally put 1 bag in it and check in a day or so to see what my intex salt water pump says. If it says salt low, I’ll add another and that’s normally all I need for the summer. My husband told me calculations showed 4 bags last year and that was way too much. I had to drain it 3/4 and refill with water.

  5. I have a 20×48 Inter radious Pool how many bags of salt do I need to use?
    How can I find out how many gallons of water is this pool?

    1. Using your 5,000 gallons, we can use the chart to calculate the salt you need. The salt chart only goes down to 8,000 gallons, finding what percentage of 8,000 gallons your pool makes u is pretty easy. For example, if you have 5,000 gallons, that is 63 percent of 8,000. So, find your current salinity level on the chart, then slide over to the value under the 8,000-gallon column. In this example, our ppm is 0, so 63 percent of 213 pounds of salt is 134 pounds.

  6. I have a round pool above ground 16ft by 3 1\2 depth how many gallons is that and how much salt do I need I already put in three bags but it shows low salt

    1. Using a pool volume calculator, your pool gallonage is 5300-6100 gallons depending on the true wall height of your pool. Using that sum, you can reference the pool chart. The salt chart only goes down to 8,000 gallons, but you can reckon that by finding what percentage of 8,000 gallons your pool makes up. For example, if you have 5,000 gallons, that is 63 percent of 8,000. So, find your current salinity level on the chart, then slide over to the value under the 8,000-gallon column. In this example, our ppm is 0, so 63 percent of 213 pounds of salt is 134 pounds.
