We just filled the pool yesterday. My readings this morning were:
FC = 0, CC = 0, TC = 0, pH = 7.2, T/A = 40, CYA = 0
I think CYA probably was actually 0 because the solution was totally clear.
Per the calculator for 27000 gallons I added 64 oz dichlor this morning. The recommended FC level for shock was 10.
This evening (about 11 hours later) my readings are:
FC = 8, CC = 0, TC = 8, pH = 6.5, T/A = 50, CYA = 0
CYA may not be quite zero because the solution was a tad cloudy, but I could see the black dot with all the solution in the tube, it just was not quite as black!
We filled the pool with some lake water and some city water.
I guess I was expecting FC to be about 0 by this evening and to need to add more shock.
Do I bring FC back to 10, or give it more time with what I added already? The water is still green.
