I dumped the first bleach in at 11am ish. 7 gal to start. Very cool things...then tons of the "goo" Have been testing about every 1.5hrs and adding...so far about another 3 gals to maintain 15ppm (according to pool math). Vacuum running, even have my daughter skimming goo off the top (it's like skimming fat off of gravy). pool only has goo remaining, i can actually see the bottom now. Working on uploading pics. I think all is going well so far.
