I need to add a bag of salt to my pool. The salt I have on hand (left to me from the pool's previous owner) is water softener salt in a yellow bag. I was surprised by how huge the salt crystals are - some are over an inch in diameter. Is this safe to use? How quickly will it dissolve, i.e. when can we get back in the pool without stepping on chunks of salt? Also, is it better to add to the shallow end or deep end, in your opinion?
SWG is reading 2700. My drop test kit reads 3000. I like to keep the salt level between 3000-3400 for my 25,000 gallon pool. We recently had a lot of rain, so I'm guessing that's why the salt level is low.
