I put it in because many folks on the old forum had reported that it just made the water feel better. And it did do that. It felt more natural, where as lots of pool water feels sort of harsh. Hard to explain.

It all dissolved in 15 minutes or so. I poured it slowly into the skimmer and you could just about pour it continuously. I guess a bag every 7 to 10 minutes or so.

If you want to try it, dump in the first couple of bags and then swim in the water. Add one at a time after that. It's easy to add a bit more and the only way to know when you're done is to go too far. So don't go much to far. It will gradually get reduced through rainfall and backwashing and refilling anyway and when you do go too far the only downside is you can taste the salt a bit more than you might have liked.
