The granules, tablets, and bleach are all just different forms of chlorine. If you use the bleach, you'll need to add the stabilizer separately, and you can lower your pH with the dry acid (pH minus). If you use the tabs, they will add chlorine and stabilizer, and will also drive the pH down because they are acidic, so you won't need the pH minus. Check the ingredient on the granules--if they are dichloro...(lots of other syllables), they will also add stabilizer and drive pH down, but if the ingredients are cal-hypo,, then you'll need to add the stabilizer and adjust your pH separately.

If you're adding stabilizer to the pool, you can either put it in an old sock and hang it in front of a return, or you can put it in the skimmer and let it go to the filter to dissolve--just don't backwash the filter for at least 4-5 days afterward, otherwise you'll just wash it all out and have to start over. If you're using the granules, you can then dissolve them in a bucket of water and then add it into the return stream where the water comes back to the pool from the filter. If you're using the bleach, it can also be poured into the return stream. With any chemicals poured into the return stream of the pool, you just have to wait 15-20 minutes or so between each chem, so the jets can help disperse it all. If you add pH minus, wait about an hour after you've added it to retest, because you need to give it time to circulate in the pool.

As far as swimming goes, after you add the chems, wait 20-30 minutes, and as long as your ph is okay and your chlorine is within range based on your CYA (and your pool is clear), you can swim.
