    Default Shelf life of liquid test kits

    I remember reading something about this and maybe it was Dave the new guy who has been keeping aquariums for many years who mention this. What is the shelf life of a liquid test kit for water testing? I have a master test kit that I bought last year. I just recently ran low on Nitrate test drops so I went and bought a kit with only the Nitrate test. I still had a bit of the old stuff left so I kept it. Every time I tested with the new drops I got ZERO nitrates which I know is wrong because when I use the old drops I got a reading of like 5ppm.

    There is a lot number on the bottle so I thought maybe I could email API and find out how old the drops are. I wish they'd just put a damn expiration date on the bottle. I mean they MUST expire sometime, right??

    Well, I just emailed the company with questions about this test kit and gave them the lot number. Hopefully they will be able to tell me something useful. If so, I'll pass it on.

    Oh, I also asked them why they didn't put expiration dates on their test kits. Seems like a logical thing to do to me.

    No telling how old mine is, it had dust on it when I got it but it works I think.

    I had a master kit go bad after maybe about 2 years or so. There certainly must be a certain span of time during which the reagents stop being quite as accurate. I would guess 12-18 months or so.
    8 tanks running now:
    1x 220 gallon, 2x55 gallon, 1x40 gallon long, 1x29 gallon, 1x20 gallon long, 1x5.5 gallon, 1x2 gallon
    Gouramis, barbs, rasboras, plecos, corys, tetras, fancy guppies, swordtails, ottos, rainbow shark, upside-down catfish, snails, and Max and Sparkles the bettas.

    The expiration date for mine is on the bottom of the box (Red Sea)

    Aquarium Pharmacueticals is supposedly on the reagent bottle I would also try the bottom of the box if it was a master test kit (it may just be pressed in not inked on)

    I got my API test kit online, and there was an expiration date on it, its on the bottom of the box. Mine expires in 10 months, but im a testaholic, so in a month ill have to buy a new one.

    To my experience, regeants start to decay after six months. Laboratory-grade regeants last two or three times that long. If refrigerated at 60 degrees they both last longer.
    I switched to electronic monitors years ago as I was tired of replacing regeants.

    I have electric monitors for pH & hardness, but that's the only to available (that I know of) for freshwater. I bought the new Nitrate monitor but found out it was for saltwater only and had to return it.

    This is a good post, none of my test bottles have expiration dates and I wondered the same as all of you.
