    Help figure salt amount

    So If i did this right, I have 2,800 gallons and then I multiply that by 0.4 = 1,120oz and then divide by 16oz I would add 70lb of salt, right?

    It is generally much easier to just use PoolMath to make the calculations for you.

    According to it, 70 pounds would add about 3000ppm of salt.

    As mentioned use Pool Math. I would suggest you go easy on the salt. You could always add more if needed. Too much and you will be draining the pool.
