Test chemical expiration dates

[bjaspan]

I have a Taylor K-1000 test kit purchased and used (for an above ground pool) in 2021. The two chemical bottles say "Best by 11/22." We are renting an Airbnb with a pool next week. Based on a poor experience we had in December at a different rented house, I want to bring my own test kit this time. My question is: Will these chemicals still give accurate readings?

I also have a SwimWorks pool test kit purchased for $5, also in 2021, but it is unopened. Might that be better because the bottles are unopened?

Thanks,
Barry

Just my $0.02 worth . . . Even if you test the rental, are you prepared to adjust, or just confirm you better not go in the water? If they maintain per industry/store standards, you might be in for the "shock" of not being in control of the sanitation process (?)

Likely. If stored in household temperature. The pH indicator would be the one that could be an issue.

The chemicals have been stored in a cool, dry basement storage room.

I do not plan to adjust the pool water, nor will I have authority to. But if the readings are way off, yes we won't go in, and maybe we can use the data to get the pool company they use to come adjust it.

I always think about the motel pools ... how many people use them without second thoughts. (I believe there are a couple of threads here about horror stories.) At least you know the drill. Good thinking.

I would not tattle based on old reagents. Pool company's first question should be to ask about the age of the reagents.
