I purchased a dozen gallons of generic bleach from my local grocery store yesterday. When I poured one of the jugs in, I noticed it was clear. I poured some in my palm and sure enough, it was just water. I took it back to the grocery store and let the clerk know. The bottle was misshapen and apparently it had exploded or something. Apparently, it was from an old batch. Just be sure to look down into your bottles before adding them to your pool. :)
