FC last night was .6, so I added qty 3, 96 oz bottles of 6% bleach...roughly 2.25 gal....so in my head, I think "pool is 18,500 gal..so...7.4 PPM FC is what it should be in the morning"...

Go back out this morning, re-test...7.4 FC..dead on....0 CC

Tonite...I get 4.6..0 CC....

CYA is hovering around 50 in my Taylor 2006C test kit...(all numbers stated have been double tested)

I am needing to add 1 gal of bleach in this Texas heat....sound right?
