    I was checking these out the other day at my local big box pet store and saw that they had expiration dates. The ones I saw were dated 06/2017.

    Do the test chemicals become unreliable with age? OR as in most cases do they last much longer than the expiration date stamped?

    TIA

    Simple answer.......Yes. They may last longer in your low humidity climate.

    I don't know the answer to that, but there is a reason for an exp. date, so I wouldn't trust it past it's date. In fact, I only keep my reagents for one year after I open the bottles -- even if they haven't expired. You never know what environmental conditions those kits have been kept under from the time they left their distribution point.

    I'm also wary of milk that's gone beyond expiry.

    I just do a smell test then taste test :whistle: We don't drink milk and only use it fro cooking so sometimes one small bottle stay in our refrigerator for a long while... some of the milk go bad before expire date and some stay fine a week later ;)

    back to the kit... I havnt test my water for what feels like ages... I need to get a new kit then :(

    What do you do to discard the chemical in the bottle?

    Well, how do you discard the chemical that you placed in the cuvettes once you've got your water reading?

    Does that make me a bad person?

    Yes it does... you should mix it in your four week old milk drink it and then when it's ready to come out dispose of it in the cuvette (what ever that might be) or the ground next to the pond,

    Yeah I think I'll pass on your milk suggestion and just keep doing what I'm doing.

    That's the way that I have always disposed of test reagents. Better to give the soil microbes a chance to work on them than dumping them directly into the existing chemical soup that we call water.

    Mitch, Mitch, Mitch. Shame on you, man.

    Do you mean to tell us that you don't wear a Type 5 Bio-containment suit for those extremely volatile, corrosive, carcinogenic and, mutagenic chemicals and then dispose of them cryogenically in order to render them inert for long-term storage in ceramic containers in the Canadian shield?

    Did you not refer to the MSDS for those compounds?

    Tsk, tsk..............

    (I hope nobody sees me peeing in the backyard).

    You're right, you're right.
    I need to do some environmental penance - you wouldn't know where I could buy a carbon credit by any chance?

    Cap and Trade legislation takes place in 2017.

    You won't see the fees, but they'll certainly be there.

    I did not realize that you upper latitude guys also had 'terms of endearment' for your fearless(?) leaders.

    Trudeau, translated literally from French means "water hole".
