I mentioned that I shocked with two bags of HTH cal-hypo last night, so I would have expected that to make the FC much higher than 5, as it was when I tested this afternoon.. SO. unless my thinking is backwards, wouldn't that mean that the FC was higher, then used up to a certain extent, making the CC level higher..?

I could be totally wrong, I'm simply making assumptions..

I just bought two 5 gal drums of liquid bleach (12.5 % sod hypo)..

How much should I dump in there..?
