Thanks! I added a total of 9 gallons of bleach yesterday. 5 gallons around noon-ish and had to get more at store, so put another 4 in around 4:00. Because I figured it needed to circulate a while to get an accurate reading, I didn't test until nearly 9:00 pm and (using the 10ml sample) used 20 drops to clear. So, 10ppm? Left the pumps running overnight.

Just retested again this morning at 6:30 am (19 drops to clear) and got a reading of 9.5 ppm. No CC.

The thing that puzzles me is after adding so many bottles of bleach, why was my chlorine level only 10 ppm when I tested last night? Now I'm wondering if I messed something up. Could that be right.....could it have been used up that quickly?

The water is clear!!! WHOO HOO! No stuff on walls either. Spent literaly hours vacuuming yesterday and after 'the dust settled', this morning there is but the smallest amount of sediment that settled in the corner of the deep end. I think that one more round with the vacuum and I'm home free.

I do have a couple of other questions. After adding the bleach, when is it safe to swim again? At what level is there too much chlorine? Also, I've noticed the water has a vaguely sticky feel to it. Or rather one's skin feels a bit sticky after putting in water. What could cause that?

Thanks again for all the help! I was ready to pull the proverbial plug on the pool last week.
