Reading through a thread which included quite a bit of conversation about bleach got me thinking. This summer I have been buying 12 121oz 8.25% jugs at a time from a high turnover Walmart. It gets me about 1.5 weeks. I store it outside though not in direct sunlight. I don't have any concern with the viability of the last jugs of the cycle since I check my chlorine every day, I know what to expect and the results will either jive or they won't and if they don't there's usually an obvious reasons why things deviated from the norm (meaning at the end of the cycle I'm not always scratching my head thinking it always takes more bleach due to being less powerful from sitting in Texas heat). Anyway, what's your opinion on my bleach storage? Would you be concerned with the strength of the last few jugs to be used? Curious. Thanks.
