How much salt should you put in your swimming pool? Provided you have a chlorine generator—that thing that turns salt into chlorine—you're going to need to calculate the correct amount of salt to add. You can't just salt it liberally, like it's a big, juicy slab of steak on the barbecue. We've assembled a list of saltwater (or salt water) calculators—some online, some that are smartphone apps—to help you get it right.

It's best to consult your saltwater generator's...MORE website for specific instructions on adding salt. If you don't recall the brand or just need a handy reference tool, these suggestions will help you with the job.
