I recently drained and refilled my somewhat-green pool at the recommendation of a pool store guy due to an abnormally high CYA level (100-200PPM?).
After refilling on Sunday, I was still waiting for my TF-100 test kit to arrive, so I put in an entire jug of liquid chlorine (from the pool store). I think it's 2.5 gal in size. Not sure about the concentration.
Today (Wednesday), I got the test kit, and here are the results (I did my best to follow the instructions exactly, but this was my first time doing this):
The pool is currently blue and mostly clear - just a tad milky in the deep end. From looking at the chart here: http://www.troublefreepool.com/conte...art-slam-shock I can tell that my FC is much better closer to 4ppm, and even the shock level is much lower than what I measured.
I am assuming that this high FC level will go down by itself in a couple days, and I plan on measuring it every day to plot its progress, but I am wondering if there is anything else I should be doing. I am afraid that my impatience is going to prevent the pool from being safe to swim in this weekend.
Edit: As noted in my later post, I did the FAS-DPD test incorrectly due to not swirling the mixture after each drop. The actual FC is closer to 12 ppm.
