Local LFS Water - Test Strip vs Liquid API

    I had to buy some more ghost shrimp today, and asked them about their water readings while I was there. They told me their water was 'perfect', but offered to test it for me - using test strips. I happily obliged, knowing I was going to re-test with my kit at home. While the readings were close for most, it was a shock regarding the water hardness.

    pH - 7.3 at the store, around 7.5 at home (7.6 on the regular tester, 7.4 on the high-range)
    Nitrites - 'normal' on the strip, zero with the liquid tester
    Nitrates - 'normal' on the strip - ZERO with the liquid tester
    Ammonia - 'normal' on the strips - .25 with the liquid tester
    GH - HIGH (300+ppm) on the strip, 7 drops (125.3 ppm) with my API
    KH - (no reading for the strip), 3 drops (53.7 ppm) with my API

    Looks to me like their water isn't cycled, anyone else think this? There are no live plants in their tanks. I was really surprised to see that the strips showed hard water when mine is not nearly so (I live less than 3 miles away from the store). I'm leaning towards my liquid test kits being correct, thoughts?

    Yeah I'd say it isn't cycled, if definitely tell the store and request they use a liquid test. Tell them that the strips are very inaccurate, I think your test would be more accurate. Those test strips are not good at all. If only use them if for some reason I needed a reading but didn't have my test kit.

    Unless the store just opened there is no way their tanks are uncycled.

    I would purchased the master test kit so much better than the strips , tossed my strips when bout my kit

    Unless they are flowing fresh water into their system at all times I would agree it seems uncycled. I think in my fish store some tanks are on their own systems including the feeder shrimp, the goldfish are separate and the Rams are separate.

    Yeah. I just tested it on a whim, the time I tested it previous it wasn't that bad - actually was close to what I expected given the readings I get from my tanks. This time I was really surprised that my liquid tester didn't pick up any nitrates and the GH/KH were way off from their strips. I guess it just helps to illustrate how 'off' test strips can be!
