I assume you have a salt chlorinator. If you don't there would be no practical reason to add salt to your pool. To determine how much salt to add you must first check the manufacturer of the salt system. A typical level would be around 3000 ppm. The next thing to know would be your gallonage which you have stated to be 1185 gallons. That is a very small pool. A small spa will easily hold 600 gallons, and I have worked on several large spas that would easily hold more than 1185 gallons.
Could it be 11850 gallons?
Double check your gallonage and contact the manufacturer of the salt system. Not all systems run the same salt levels.
For a non-INTEX pool you need 50 lbs. of salt for 2,000 gallons. or water capacity in gallons X 0.025.
It depends on the size of your pool. My pool is 18 x 36 inground, approximately 24,000 gallons. We put in 600 lbs. of pool salt, when we started.
The answer is 208 lbs of salt. The equation is roughly 26lbs per 1000 gallons.

If you have a "chlorine generator" that requires salt in the water, ALWAYS refer to the manufacturers recommendations for the proper amount.
You need to know how what size your pool is. But to raise your salt level 1000 ppm, add approximately 80 lbs of salt for every 10,000 gallons of water. Adjust tequila and lime to taste.
For a saltwater pool, the standard requirement is around 3200 ppm (parts per million) of salt. To achieve this in 23000 gallons of water, you would need to add approximately 161 pounds of salt. It's important to use a salt measuring tool to ensure the correct amount is added.
Assuming you have a chlorine generator and actually need to add salt, the amount is determined by the manufacturer of the device you purchased. Looking in the instruction manual will tell you what the required sodium level is for your particular unit (somewhere around 3,000 ppm is typical). Then you must test the water to see what the sodium level is currently. The difference is what needs to be made up. It takes roughly 25lbs of salt per 1,000 gallons of water to go from zero to 3,000 ppm. So you need about 112 lbs if your 4,500 gallon pool is at zero ppm now. Pool & Spa
This needs to be tested with a pool salt testing device or get the water tested at the pool shop.
Follow the instructions on the bag of swimming pool salt based on the size of your particular pool. k
It depends how many gallons your pool is. Once you buy your chlorinating system, the install manual will tell you how much salt to add based on how many gallons in the pool. I have an Autopilot Digital and it tells me when it needs salt. I still check it with test strips to be safe.
40 lbs per 1000 gallons use pure water softener salt just pour it in the leave pump runing pool will start clearing up the first day salt will be gone over night . more is not better do not exceed this formula it will not speed up this process. i have been using this formula for ten years with no problems
