Got back from vacation this afternoon. A quick sweep to be sure we hadn't been burgled, then to look at the pool. It's still sparkly! Whew!
I pushed the Chlorine up to 17 about an hour before we left, it dropped to 8.0 in a week - a little below target for me, but no green. No CC. pH went up, no surprise there.
Water level dropped about an inch, which was a relief. I was afraid it would drop more than that.
I had a last look at the green pool at our hotel on our way out this morning. I could see the where the bottom step met the floor, which is actually an improvement. Yesterday morning I saw a woman standing in the pool, and I couldn't see her feet.
What a contrast.
