Thank you all for your help.

The water is now blue, but not clear. You can see about half way down.

Right now the free chlorine has been right around 20ppm the past 36 hours. Our ph is still a bit low - right about 6.9-7.0 We will be vacuuming it again later today. We keep adding about 2 cups of borax each day and it is still low.

My question now is should I use some of that 'clean and sweep' stuff that I have. It is supposed to bind everything and drop it to the bottom so it can be vacuumed up. And if I do use it, should we vacuum first and then use it and vacuum again or just use it and vacuum once?

And last time I checked my alkalinity was nearly nothing (see first post) - is this why my ph is staying low? Should I add some baking soda to get it up & if so how much?

Now that the water is not green, should I let the chlorine drop? Do I just unplug my salt water generator for a while and have it naturally evaporate? Or should I add something to bring the chlorine down? My kids are anxious to swim.
