I just realized my Pool Chlorine is more deteriorated than I had calculated. I adjusted Poolmath bleach % until 9.5 oz predicted the +10 FC that that dose yielded for me. I revised the last two weeks worth of Bleach %'s to 4%.

With FC at 0.0 ppm and water was cloudy. I am trying to raise CYA from < 1 ppm, hoping to get to CYA of 30 eventually.
I am going away for 5 days...
I added 1.2 oz of Dichlor to raise FC from 0 to 16 (per P'Math).
At 12:50pm, TA jumped from 50 to 80!??? FC 14.2, pH 7.4

For first time, tub had larger 'bubbles' (I assume from deterg.) and smaller 'foam' (I assume from bather's sweat, etc.) Foam scooped out for 5-8 mins.

I forgot to test pH & TA 'AFTER' adding the Dichlor & Bkg Soda. I did not know Borax would lock pH where it was (Way above 8 bright red) when Borax was added. :o0

pH
Decided to add Borax. PoolMath said to add 20 oz (by wt.) or 19 oz. (by volume). BUT when the measuring cup on the scale got to 19 oz of Volume, the weight was only 13 oz. WTH? I added this 19 oz vol./ 13 oz wt. to the tub.
