Benchmarking a possibly-expired test kit

[FormerBromineUser]

...CarlD..: (and) I quote, "So, if you pour 1.88ml of bleach/liquid shock/liquid chlorine into 5 gallons of fresh water, you should get the same FC reading as if you dump 1 gallon into 10,000 gallons of water." .

Well, again I was hoping Carl would chime in... but it sounds to me like you reagent is too old.

Are you anywhere near a border to the US to get a kit? If not, get an OTO or HTH 6-way test kit.

How is your pool looking? Does it feel slimy at all?
