I have two different R-0871 bottles that clearly have different drop sizes. Easy to tell just by looking. One gives 10 ppm FC and the other 7 ppm. Assuming the 7 ppm is correct for the time being.

Controlled test results: control water was at 6.5 ppm this morning. Calcium-dosed water was at 3.0 ppm.
Doing a controlled test to see if my calcium chloride triggers a decrease in FC. Both samples started at 7.5 or 8.0 ppm of FC and around 200 ppm CH. To one sample I added enough calcium to increase the concentration by about 280 ppm. The other was left alone.

The digital pH meter has been leading me astray I think. It is 0.3 units different than the Taylor kit reads. Ugh. Fixing my pH with soda ash.

I added pH down then pH up. The down was to bring the alkalinity down, but the pH didn’t rise as quick as I hoped with aeration. Had to resort to some pH up before I put the cover on.

This bleach I’m using is very old, about 1.2 years according to the stamped date. Is definitely not full strength, more like 4% rather than 10%. Bad local store for selling me such old product.
