Brown gunk on the bottom of pool

Did you get alot of rain while you were trying to raise the pH? Irene maybe? My pH went from 7.5 to 7.2 in Sunday's storm. If it was the storm, yout TA probably dropped too, not that you should adjust it, just what acid does to a pool.

I didn't get hardly any rain from Irene, but I got about 1-1/2" Monday after she was long gone, which will probably make my PH and TA worse. I had checked the PH before Irene was supposed to hit just to beat the storm. I've been dissolving the Borax in a bucket of water and then dumping it in the pool, so I don't think it is settling to the bottom or anything.

You don't need to pre-dissolve the Borax. Just pour it slowly into the skimmer breaking up any clumps.
