I wouldn't lose any sleep over getting the water super clear - for the leak detection people, that is. Perhaps they just want clear water so their technicians don't have to get in a green slimy pool??? Doesn't sound like that's what will happen anyway. I don't think a little cloudiness should bother them.

Good catch on your water loss. You're doing the right thing to call a leak detection company; they'll take care of it on Monday. In the meantime, follow CToon's advice and enjoy your kids.
